Transparent epoxy resin for filling: the material for creativity

Supporting universal theoretical rejection of the use of objects made from synthetic materials, yet it must be admitted that certain chemical compounds are indispensable in our Everyday life. These include a transparent epoxy resin for filling. Admiring the outer Natural Artificial amber or radiant purity countertops "stone", do not even think about the origin of the material.

What is an epoxy resin, material specifications

Resin - a substance that hardens under certain conditions. Distinguish natural gums (wood) and synthetic. Epoxy (abbreviation of "epoxy resin") is a polymeric resin, i.e. the chemical composition of oligomers - small molecules with limited weight.

Main characteristics of the substance:

• resistance to moisture, ultraviolet;
• not exposed to acids, alkalis, halogens;
• soluble in acetone and esters;
• no harmful volatiles.

The composition transparent epoxy resin - Linings. The end product obtained during the implementation of two chemical processes. In the first stage creates a low-molecular weight linear thermoplastic. The second, which is the curing by obtaining spatial structure therein formed hard, insoluble and infusible substance.

The ability to quickly turn from a liquid to solid is a very valuable property of the epoxy resin. In addition, it can be firmly glued surface. The set of characteristics and makes the structure of the above-mentioned demand.

Basic methods of usingtransparent epoxy

Scope of the epoxy resin sufficiently broad. The substance is widely used both at home and at work. Constantly improving processes, getting more and more new formulations with improved properties increase the range of applications.

Traditionally, resin casting is used in various industries for the following purposes:

• for impregnating glass, gluing parts. Scope of use: construction, aviation and mechanical engineering, electronics, electrical engineering, manufacture of fiberglass, repair ships and automobiles;
• to create a waterproofing layer. The material used for the coating of walls of buildings with high humidity, basements, pools, reservoirs and other liquids;
• if necessary create chemically resistant coatings for internal and external surfaces, and for applying a protective layer on the porous material;
• to fill in the form in order to get clear details and objects, which can then be cut, sanded, ie machining.

Useful advice! If necessary, glue solid surface is better to buy a special epoxy adhesive, and not use any resin composition. Connection effect will be, in any case, but special material allow for a process more efficiently and effectively.

Baseline characteristics transparent epoxy resin

Almost all kinds of epoxy resin in the initial state are transparent. Some may have a yellowish tint. After connection with the hardener yellowness disappears. This is sure to be considered, if necessary, have a transparent epoxy layer.

Some types of the polymer having a high viscosity, bubbles form after curing, greatly reducing the effect of transparency. You can get rid of them by heating, which must be done before or after filling it in the latter case, apply the burner or other heating system. This process is quite troublesome and does not always produce perfect results.

Finished articles made of epoxy resin over time can lose transparency when exposed to ultraviolet light and oxygen contained in the air. Such troubles can be avoided only if the resin used to the presence of UV-protectors and antioxidants.

Consequently, the choice of the epoxy resin to obtain a solid, transparent material must be considered:

• hue resin prior to making additives;

• the viscosity;
• chemical composition.

Transparent epoxy resin can be used for the manufacture of small parts (jewelry, souvenirs, decoration) and for larger castings (table tops, shelves, and so on. D.). Technology of Epoxy application can vary depending on the particular products.

Useful advice!To be sure (especially when running large fillings) that the resin composition is suitable for your goals, it is better to buy a sampler - a container with a small amount.

Features of the preparation process of epoxy resin for potting

Preparation of epoxy resin composition should be in accordance with the instruction, which in one form or another attached to each container. The lack of description of the sequence of actions indicates questionable quality of the goods, which will certainly also does not have the certification.

When mixing the epoxy resin proportion playing the most important role. Standard ratio of resin and hardener - 10: 1. the proportion may vary in special formulations from 5: 1 to 20: 1. Methods for the preparation of small and large amounts are also different. For a small amount just enough agitation. A large mass of pre-should be heated to reduce the viscosity. It should be borne in mind that an increase in temperature to 10 ° C accelerates the polymerization of at least two times.

Preheating the resin is required to control the temperature readings. If the substance begins to boil, it begins to foam, thicken. Such a composition is unsuitable for use. To reduce the viscosity by using diluents. Note that even 5-7% of such additives in a composition significantly reduces the quality of the material.

The problem is clear, that is, the dissolved epoxy resin retains its relevance. It is better to prevent complete solidification spots. If, however, it was the most effective way is mechanical, but it does not apply to all surfaces. Using special solvent resins also provides preservation surface. If conditions permit, you can apply heating or freezing.

None of the methods does not guarantee complete purification.

How to make an epoxy resin in the home

Epoxy resin in the home cook simply. This requires to prepare the necessary container, a volumetric capacity and a stick (or other similar object) for mixing. The process of making epoxy resins with their hands involves several stages:

1. The choice of premises. It must be ventilated, having a temperature of about 25 ° C and low humidity.
2. Performance of the test compounds. It should be mixed in a small amount of epoxy. If the characteristics (transparency, viscosity, curing time) satisfied, it is possible to move to the full volume.
3. Using method of cold mixing. 10 parts of resin necessary to add one part hardener. Stir follows with the same intensity and in the same direction - in such a case, the mass will be more homogeneous.

Useful advice!At home, the large volumes (more than 5 kg) is better not to cook. When mixing is allocated a lot of heat, which accelerate the polymerization and quickly make the composition unsuitable for use.

To understand how to make the epoxy resin soft enough, you should also perform a test connection, taking into account all planned for the use of fillers.

Hardeners for epoxy resins: functions, types, application features

The importance of correct application of hardeners for epoxy mixture mentioned above. To understand how to dissolve the epoxy resin and hardener, it is necessary to know the quality and distinctive properties of the latter. That is determined by the characteristics of the additive composition of the characteristics as a whole.

Hardeners for epoxy resins of the chemical features are divided into two types.

Amine. They include amines, diamines, polyamines. This is the most common curing agents, which are often used in everyday life because of ease of use. They do not require the creation of certain temperature conditions, the process takes place even at room rates. This method is called cold curing.

Acid curing agents. It is based on the acids and their anhydrides (maleic, phthalic, hexahydrophthalic, and others). It should be noted that the quality of the solidified layer in the presence of acid additives is much higher. However, the application process is much more complicated, as it requires heating (100-200 ° C) weight to improve its physical and chemical properties. This method is called hot curing.

epoxy resin price (complete with filler) largely depends precisely on the type of hardener.

Useful advice!Given the importance of the curing agent for the quality of the end result, not worth saving on the price and purchase cheap types. Better to buy options that are recommended by the manufacturer for a particular type of epoxy.

Can I make a hardener for epoxy resins with their own hands

Applying epoxy resin requires exact observance of certain technologies. Therefore it is better to use a ready-made formulations. A situation where the epoxy resin remains and the curing agent is used up, are quite common. Is there an alternative, that is, the component is possible to make yourself? It is possible, but only on the condition that will be purchased and the necessary chemical components are connected in the right quantity.

In commercially available can be found Etal-45M, CHS-Hardener P-11, Telalit 410, diethylenetriamine. The quality obtained in the course of homemade hardener is certainly worth a test to evaluate the way that is blended with resin in a small amount. To understand how to dissolve the epoxy resin and hardener is a test, you can use the following tips and algorithm steps:

1. Prepare a small container and two dimensional nozzle or syringe. When using syringes easier to monitor quantitative indicators of liquids.
2. A syringe type in a certain amount of resin poured into the container. Then type in another syringe and hardener in a ratio of 10: 1 to introduce it into the resin.
3. Intensive post composition, but without the use of electric mechanisms, leave to harden on the alleged use of surface (or similar).
4. Watch polymerization process. If necessary, an adjustment should be made to the same method, but using other proportions.

The hardener dry alcohol can be used at home. It should be ground and connect with the resin in a proportion of 10: 1. This method is also to be tested in small amounts.

Important!Linking agents necessary in such sequence as mentioned above. Otherwise, the polymerization process can be accelerated and will not give objective results.

Plasticizer as a filler for epoxy resin

Along with the hardener essential component is an epoxy resin plasticizer. Products made using such a filler, they do not crack or break. Be sure to add a plasticizer when using large amounts of epoxy, that is, to create thick layers, since cracks can form even in the process of solidification.

One of the plasticizers for the epoxy resin is dibutyl phthalate, abbreviated - DBP. The substance is difficult to mix the resin, so the level of low plasticity. Additives is sufficient to protect products from cracking during solidification, from low temperatures. To enhance the effect of mixing resin and plasticizer is carried out in a water bath.

More effective plasticizer recognized Laproksid DEG-1. It in itself is an epoxy resin, mixes well, the addition of 5-7% gives excellent results. Composition with DEG-1 (without hardener) can be stored as long as you want.

Actively used to plasticize the epoxy resin S-7106 thinner. When you add it is necessary to use a curing agent in the usual proportion to the total composition. That is, to 10 kg of epoxy and 100 grams of diluent should be added 110 g of hardener.

Adhesive epoxy material may be rigid and ductile. Hard are composed of resin and hardener. Plastic produced with additives inhibiting solidification process, but provides a stronger adhesion. Simple answer, as drying epoxy adhesive with a filler, it is impossible. much time depends on the temperature conditions. If no process upset, the maximum value - 24 hours.

Products made of epoxy resin: jewelry, furniture, decor

Transparent Epoxy Resin - means multifunctional. Using it, you can perform complete articles that decorate the model of a different material, to connect the individual parts into a coherent whole. art processing effect is present in any element, where such a polymer is used. Transparency gives similarity with glass. This property contributes to the widespread use epoxy to create souvenirs.

Bathed in natural materials: leaves, flowers, buds, grain, etc... - become interesting crafts. Epoxy amenable tinting, which allows the use of material for the manufacture of various ornaments. Exclusive pendants, earrings, clips, brooches, hair clips and other accessories are very popular with today's fashionistas. The material properties allow to create imitation gems that only experts can distinguish from the natural.

Modern design development - epoxy resin furniture. Original and durable countertops, shelves, decorative elements backs, legs can be seen in the interiors of buildings of various styles and directions. Recently, transparent epoxy resin was used for the creation of sex with 3D-effect.

A variety of products of epoxy resin and wood

Epoxy resin and wood - perfect both from the aesthetic and from the practical point of view the combination. The polymer composition fills the pores of the timber, provides a secure connection and forms a solid coating or insert. Price epoxy high, but given the quality of the handmade jewelry or furniture exclusive options, the use of the chemical composition is fully justified.

The epoxy resin can fill wooden mold contours or create top layer. The first method is often used in jewelry manufacturing. Hollow rings, hearts, stars, leaves, and so on. D. filled with colored or transparent composition, resembling amber, emerald, ruby, or simply creating a volume.

The second method is used in the manufacture of furniture. The layer of epoxy is applied to the substrate, resulting in the original table top. The decor can be used as different subject inserts.

Of wood and epoxy resin made shelves, flower stands, vases. Products can be illuminated by fluorescent or fluorescent additives introduced directly into an epoxy compound, or by a LED strip.

Useful advice!In the manufacture of articles made of a transparent epoxy resin and wood to be prevented that the resin layer wood processing waste. This can significantly reduce the effect of transparency.

Original products of epoxy resins with their own hands

Epoxy resin allows us to implement creative ideas without spending a lot of time and effort. As mentioned above, the transparent part is easy to prepare yourself. Then you can create an exclusive jewelry - a bracelet on his arm. This will require:

• Transparent polymer composition;
• forms for epoxy resin - Molds;
• inlay (dried flowers, coins, artificial or natural stones and so on. d.).

It is necessary to lay out in the form of decoration, pour the mixture, using a toothpick to correct a substantive insert, remove bubbles (if they were), let cool. The finished product should be roughened (a router can polish) varnish.

It is easy to make an epoxy resin unusual shelf backlit. To do this you need a piece of edging boards, for grinding tools, resin, hardener, luminescent powder. The steps of manufacturing the shelves:

1. Board sanded to remove the bark and loose knots. The more defects in the wood, the more original to obtain a product.
2. Dilute resin entering all excipients, fill cracks and depressions over the entire surface to cool. If defects are on the edge of the workpiece, required limiting rim, which must first be made of a thin metal plate or wood.
3. Grind the product and hang on the wall.

It is worth to count how many there are epoxy resin, fillers and a piece of edging boards. It turns out the amount corresponding to the most inexpensive chipboard shelf, but decorative products are incomparable.

Transparent epoxy resin for castingTips For beginners

Skill comes with experience. In the case of epoxy resin is especially true since many need to try and test. It is useful for beginners are some tips to help you quickly master the so affordable at first glance, but enough capricious material:

1. Transparent epoxy resin price is high - from 800 to 10,000 rubles per kilogram, depending on the destination and the chemical composition. That the costs were not in vain, to start any job is worth a test.
2. When using the forms to fill need to lubricate them with petroleum jelly for quick extraction of finished products.
3. It is required to close the work surface where it will be carried out fill, oilcloth or thin wood plates. The paper does not provide the necessary protection.
4. In the case of formation of the epoxy resin in flakes or pellets should be heated liquid but not more than 60 ° C.
5. When a stiffening layer bubbles can easily remove them by inserting a straw and dunuv therethrough.
6. It should be a balanced approach to the low epoxy value. Products made of this material can quickly turn yellow. It is necessary to look for on the packaging or container a mark "UV filter".
7. Before using the transparent epoxy resin harm will deliver it to the closed heat source such as the battery - the composition will harden.

Useful advice!When buying a transparent epoxy resin should pay attention to the expiration date. Standard rate - 12 months. If it is less, the composition is likely to have low-quality characteristics.

How to use an epoxy resin: safety regulations

Epoxy resin, like many other chemical compounds requires careful treatment with it, subject to certain rules. They mainly relate to the composition in the liquid state. Some epoxy components can cause burns, dermatitis, poisoning, hitting the upper respiratory tract. Knowing how to work with an epoxy resin, it is possible to avoid damage and injury. Basic safety requirements:

1. It is impossible to produce a mix of ingredients in a pot, intended for cooking.
2. Before working with epoxy resin, wear protective clothing, including gloves. Hands on a pre-sunscreen should be applied.
3. Work on the machining of hardened material to be performed in glasses and a respirator.
4. If the epoxy still gets on your skin, you should immediately wash it off with warm water and soap or a swab dipped in denatured alcohol.
5. Working with epoxy resin can be carried out only in those areas where forced-air ventilation is organized.

Despite the saturation of the market, there are all new and new epoxy compositions. This material is tough competition for wood, glass, metal, ceramics. Products of durable, reliable, long time do not lose their aesthetics. In addition to the high practicality, transparent epoxy resin makes it possible to create interesting interior.
