The density of the epoxy consumption and use of technology

Chemistry - the science complex, and not everyone has the knowledge in this field. However, one who works with the chemical composition and allows them to flow in certain processes, must have an idea about your material. The density of the epoxy resin in the finished product will be high only if the components are properly selected and optimal conditions for the polymerization composition.

Epoxy: variety of chemical compositions

The use of epoxy for a long time and become a part of our lives. In the home, where it is necessary reliable connection or solid composition, this agent is indispensable. Epoxy resin - is one type of synthetic resin, oligomer containing epoxy groups. The substance has a complex chemical formula.

Depending on the composition, there are several types of resins:

1. Epoxy-diane. Have markings ED-10, ED-16, ED-20, ED-22, VC-SM-PRO. They are widely used in everyday life and in the industrial sector. Compounds with impregnating function, self-leveling floor, adhesives - not a complete list of the application of this type of polymers.
2. Epoxy-diane intended for the manufacture of varnishes and paints. These epoxy marked E-40, E-40 R. With them are durable coatings.
3. Epoxy-modified (Epofen 1,2,3). They are used for repairs.
4. Special epoxies. Properties formulations (with chlorine, resorcinol, and so on. D.) Making them suitable for specific conditions.

Any epoxy resin composed of two components - a resin directly as a base material and hardener. Various fillers impart certain qualities composition.

The main consumer properties of the epoxy resin

epoxy resin cost is quite high. Buy a small amount for domestic use is quite accessible, but significant volumes require considerable financial expenses. However, the growing popularity of the substance. This fact can be explained by the presence of good consumer properties of the polymer. Among the main characteristics are the following:

1. Strength. At high levels of processability and manufacturing processes use a frozen resin may compete with individual concrete marks.
2. Thermal stability. The epoxy resin can withstand a temperature of 200 ° C and above.
3. Water resistant. In the solid state the substance does not absorb water.
4. Adhesive properties. The high level of adhesion and strength glue joints allow large surfaces.
5. Resistance to many aggressive chemicals.
6. Light weight products.

These characteristics are common to all types of resin. These qualities are manifested in a greater or lesser extent depending on the additives used in the preparation of epoxy.

Useful advice!Acquiring epoxy resin is required to be determined (independently on the basis of information on packaging or ask a specialist to sell the company to provide product information) purpose composition. Even a slight mismatch can affect the final result.

Modern applications epoxy resin

The emergence of new formulations continuously expands the range of application of epoxy resins. Since you can not just glue the items and create decorative items, furniture using polymer materials data, but also to replace a considerable size metal structural elements and mechanisms, cutting the cost and reducing the the weight. The main fields of application of epoxy include:

1. Production of composite materials. Using the method of impregnating synthetic fabrics, fiberglass and carbon fiber are produced. The material obtained is lightweight and durable. He is actively used in the simulation, to create machines, missiles, ships and aircraft.
2. Manufacture of furniture. This options like in-line (mostly kitchen countertops) and exclusive (tables of slabs, countertops - river, maps, pictures, etc...).
3. Creating insulating and waterproofing materials. Epoxy resin is a dielectric, it liquid-impermeable.
4. jewelery production. Jewelery of epoxy (pendants, bracelets, brooches and the like. D.) And differ cheap decorativeness and aesthetic.
5. Repairs. You can pour epoxy cracked countertop, make a new floor, eliminate leaks in the boat, to repair the vehicle body using fiberglass, and so on. D.
6. Production of various handicrafts, souvenirs, scale models.

Working with epoxy resin is much easier than, for example, metal or ceramic.

Production of Epoxy Resin: addition to instructions

Epoxy always comes complete with a hardener, because without it, the bulk liquid hardens. All information on how to make epoxy, can be found in the instructions of use. Some important moments manufacturer still does not light, so it is worth to say about them separately:

1. The quality of the final product affects both the lack and excess hardener. With a deficit of weight will be characterized by stickiness. Excessive amount of the additive will accelerate the polymerization process, but will lead to cracking of the material.
2. Stir components necessary object without having the additional elements (blades, whisks, curved and so on. D.). Such devices speed the flow of the curing process.
3. epoxy toxicity manifests itself in a liquid state, but it is insignificant, because ventilate the room enough to create a safe environment.
4. Should not enter the fluid in the individual components and the finished part.
5. Kneading is necessary that amount of material that can have time to develop before the start of the solidification process. If, however, epoxy prepared much better pour it in small amounts in various containers - it will keep longer required viscosity.

Useful advice!In the preparation of resins for different types of work is necessary to observe certain technology, including the right choice the composition, temperature, sequence of actions and timeframes.

Technological intricacies of the epoxy resin

Since the mixing and prior to its solidification active is 40 minutes, which requires time to be spent composition. In operation, the resin may be used as an adhesive, for applying the top layer on the base, for filling cavities or special shapes. Based on the target, must get involved the required amount of epoxy resin.

It is important to know the flow of the polymer. Particularly relevant to the exact figure when filled with large horizontal surfaces. For example, the flow of epoxy resin 1m² countertop - 1 liter (or 1.1 kg) with a layer thickness of 0.1 cm. This amount without additives. And the average value may vary depending on the polymer producer.

Optimum layer for curing epoxy - 1 cm. A thicker coating may crack during solidification. If a thick layer is required to fill - 2 cm or more, it is possible to do this stepwise, applying the composition in divided doses. For larger volumes, you can choose the epoxy resin and hardener.

It is important to properly prepare the surface to which the polymer will be applied:

1. Dedusted.
2. Degrease. If the solvent is used, it is necessary to remove it and wait until evaporate residues for this purpose, ie, the surface is dry.
3. Wooden parts should be cleaned skin. This will create roughness, which will increase the contact area.
4. Metal surfaces must be polished to a shine.

When bonding portions must pull design clamps.

Tips on making a colored epoxy resin

To be sure of the result of the dyeing of epoxy resin, it is better to purchase specifically for this purpose means. You can find them in the shops and art galleries that sell the appropriate products. ink types may include the following:

1. Monochromatic. Epoxy impart a specific color (blue, red, purple, and so on. D.).
2. Fluorescent. Due to the presence in the composition of the phosphor products acquire a glow effect. They can also give additional color shade.
3. With the effect of the haze. Absorb gloss material.
4. Metallic. Products acquire a metallic sheen.
5. With sequins. Frozen epoxy mass poured.

The photo epoxy resin in the Internet are shown as the types of dyes and finished products with their application. You can select the color option. View products depends largely on the amount of injected dye. A few drops will maintain transparency, give a light tone. By increasing the amount of the dye, it is possible to get more vivid colors. To achieve a bright, deep shade, you should first paint composition in white color, and then add the desired shade.

Useful advice!In order to avoid difficulties in handling dyes, better to buy the means of the same manufacturer that produced the epoxy resin.

Epoxy resin for creativity: features, major brands

One of the qualities of epoxy resin - transparency - allows you to use this material for creativity. Such compositions are used for the manufacture of 3D-paintings, original tops, jewelery, decorative interior. How wonderful epoxy casting compound is used in the creation of herbaria and various exhibition models of natural material. Natural flowers and dried flowers, exotic species of insects, mineral samples acquire additional originality and exoticism of a transparent polymer layer.

When choosing the material for creativity important class of epoxy resin. The most popular transparent formulations are:

Useful advice! When purchasing resin for creativity, you need to be sure that it is resistant to yellowing.

Products made of wood and epoxy resin with their hands

In the Internet a large number of pictures taken by imaging articles made from epoxy resin or with the use of the substance. A significant number of them are made of wood and resin. Wood is often preferred because of its high level of environmental and natural decoration. Even rough surfaces may be perfect interior elements, and in case of additional materials decoration their value increases.

Any wooden surface, even a perfectly polished, has pores into which penetrates the epoxy, creating a strong bond. Therefore, the combination of materials is a good one for the manufacture of exclusive furniture. Epoxy for potting or bonding wood surfaces often used transparent. It can also be tinted according to the design plan.

Independently produce products of wood and epoxy resin snap. As an example, you can take an idea from the Internet. On the selection and preparation of the epoxy composition in the article mentioned above, but a few tips home handyman will come in handy:

Epoxy Resin Density: standard and actual indicators

Epoxy resin is stable to alkali, halogen and some types of acids. This quality is provided a composition and basic properties. The substance in pure form, without hardeners, has the following characteristics:

• elasticity of 3000-4500 MPa;
• the tensile strength is 80 MPa;
• the density value is 1.2 g / cm³.

Main unit, which measures the density of the epoxy resin - g / cc (kg / m³). The indicator value may depend on the following factors:

1. The temperature. Products obtained hot-curing denser.
2. From the presence of air. Bubbles in the composition of the epoxy layer reduces the density.
3. On the presence of the pigment additives. Dyes, giving the decorative materials, reduce its density.
4. From hardeners quality. When using acidic additive material density higher than after application of the alkali.

epoxy Density (kg / m³ or g / cc) - one of the main indicators of the strength of a solidified material. If during the operation carried out from a polymer product will experience considerable mechanical loads, it is necessary to pay special attention to this value.

Useful advice!Determine the density of the finished composition of epoxy resin in the home is almost impossible, it requires a laboratory. Consequently, to achieve the optimum value can be only under the processability during operation with the polymer.

Technical indicators epoxy resin ED-20: density, viscosity, temperature

Wide application as in the workplace and at home received epoxy resin ED-20. It is a liquid substance yellow or brown, which has no additives.

Polyester resin: how to work, the composition of the toxicity

In the industrial production of a large amount of resin applied. In everyday life, the most acceptable - epoxy and polyester. Both options - thermoset plastic after curing they can not return to a liquid state. The process of polymerization of polyester resins starts at the stage of their manufacturing in production. Reaching complete curing agents, the reaction is only accelerating.

From this we can conclude that the polyester resin has hardened and without additives, but especially important to the shelf life of the composition. Of the main advantages of polyester resins can be identified:

• low cost;
• fast curing;
• lack of intensive change in viscosity.

The level of low harmfulness polyester resin, although the polymer is quite pronounced odor. Prolonged contact and indoors composition may cause irritation to the upper respiratory tract and redness in contact with skin. Work with polyester resin is easy. Curing agent, accelerator, or rather, it is necessary to pour in the manufacturer recommended proportions, stir the non-intensive (it will help to avoid the appearance of bubbles) for 2 minutes.

The curing agent in the polyester resin serves as a catalyst, i.e. when it is added exotherm begins, activating the polymerization process. You can not make additions to this type of resin, and the use of external heat sources.

Useful advice!It is not necessary to apply a layer of epoxy polyester resin - fibered substance.

Whether harmful health epoxy resin and how

As for the epoxy resin, is constantly used the word "chemical", "synthetic", "reaction", "polymerization" and more complex frightening names of substances. Association is not difficult to guess - a solid chemistry, and therefore harmful. The contents of the article have already been attempts to illuminate this question, but it is so important and urgent that is worth looking into it more thoroughly.

Once again I would like to draw attention to the fact that the harmfulness of an epoxy resin is due only to its liquid state. Inhalation may occur discomfort in the stomach, headache, cough. All this it is easy to avoid, if you work in a room with ventilation, and more reliable - a respirator. With infrequent contact with the composition of the problems usually arise. Those who are engaged in industrial production, the most protected from the effects of harmful substances.

After curing the epoxy resin is nontoxic. When carrying pendant or bracelet caused some backlash, this is most likely due to the individual characteristics of the body, with an allergic reaction to the specific substance. In most cases this material on which the decorative coating formed articles, rather than the main part.

To avoid getting resin on the skin, it is necessary to work in gloves with rubber or other similar impregnation. The epoxy resin does not cause burns, but remove it should be in contact as soon as possible: because of the body temperature it will begin to solidify, and then remove it will be more difficult - need solvents, which are much more toxic resin.

To some extent, working with epoxy resin - a method of trial and error. This article contains information that will help at least partially avoid the problem. If the desire is correctly updated workflow, knowledge characteristics of the materials used, the result is bound to be good.
