Heat Resistant Sealant - Key Features of
Every day, our kitchen equipment, as well as furniture, is exposed to the adverse effects of water, all kinds of liquid and solid products, which leads to its damage and premature failure. In order to avoid all this during installation, as well as repair of hobs, ovens, electric and gas stoves, care must be taken to seal the connections.
The ideal solution to this problem is the use of specialized sealants that meet the requirements:
- heat resistance;
- longevity;
- the ability to seal and glue various materials.
And this composition is - high-temperature silicone sealant .This type is produced in a pasty state, which allows it not to flow off vertical surfaces during application. In addition, it has excellent adhesion to a variety of materials, vulcanizes at room temperatures, is resistant to aggressive substances, retains elasticity, and also stability at temperatures from -45 ° C to + 270 ° C( with possible short-term increases to critical + 350 ° C).
Heat resistant sealant - why is it widely used?
Object of our conversation is also used for sealing fireplaces. Fireproof sealant is a viscous mass with very high heat resistance. Compositions of this kind are usually used for industrial use, but sometimes it is indispensable in everyday life.
The main and most popular type is the heat-resistant silicone sealant, which is based on silicone rubber. There are also less popular polysulfide, urethane and acrylic sealants with a specific field of application.
The color scale of this building material is also striking, which is remarkable for its amazing variety. Saving on this form of sealant is absolutely not advisable, becauseit can depend on the degree of your well-being, because low-quality sealants can contain harmful chemical components that are released under high temperatures and enter the air. Therefore, it is worth paying great attention to the quality of packaging and the cost of the goods, becauseA quality sealant of this kind can not be cheap.
High-temperature sealant penetrates even the deepest cracks and gaps, because it is a flowable material with the highest degree of elasticity. It is intended for sealing and gluing both metal and non-metallic surfaces, to protect different equipment from moisture and chemical attack, to fix joints of pipelines.
Heat-resistant sealant - how to work with it?
Preparing the substrate for the use of high-temperature sealant does not differ in originality and complexity. The surface must be cleaned of dust, dirt and bitumen. Also it needs to be degreased with acetone or another solvent, remove all the remnants of the previous old sealant, if any. Protect the rest of the surface from contamination by gluing the paint tape.
Cut the tip of the cartridge just above the thread, place the cartridge in the construction gun and apply a fireproof sealant to the surface. To apply it is necessary under pressure with the purpose of reception of stronger adhesion. After that, level the surface with a wet spatula, remove the paint tape and leave the seam to dry for 24 hours.
