During operation of heating systems and other various appliances, cracks begin to appear. Close them up only with special tools that can withstand high temperatures. These materials include high-temperature sealant. Consider all its features and characteristics.
What is a sealant. Types of High Temperature Sealants
High-temperature sealants are a specific type of sealant used to process joints in automobile engines, pumps, gearboxes, and in heating and ventilation systems. Such sealants work well with the following materials:
- Glass.
- Enameled surface.
- Ceramics.
- Tree.
- Metal.
There are several main types of such sealants:
- Acetate silicone based high temperature sealant. They are used for sealing joints and joints that are constantly at high temperature from 250 to 300 degrees. It is mainly used for industrial purposes. Categorically can not be used to treat seams that are constantly in contact with gasoline. Such a sealant is available in three colors: black, red, beige.
- Silicone based high temperature sealant. It is used for joints and joints that are at temperatures from -50 to +250 degrees. With constant temperature jumps, its properties do not change. used with many surfaces, even glass and metal.
- High-temperature sealants on a one-component basis. This type of material hardens from air humidity. Use it at temperatures from -65 to +300 degrees. Sealant is used to repair metal parts, pumps and kitchen equipment.
- Sealant for fireplaces. It is made of fiberglass. Sealant is used to repair fireplaces, stoves, furnaces and chimneys. It can also be used to repair the exhaust system of cars and motorcycles. It is strictly forbidden to use for repair of gas equipment, central heating systems. The fiberglass sealant after drying becomes hard as cement. Accordingly, he does not sit and sit. You can fasten materials such as metal, brick, concrete.
- Elastic high-temperature sealants based on polyksilosan. Withstand temperatures up to +285 degrees. This sealant can replace cork, fiber, paper, asbestos or rubber. The consistency is red paste.
Sealant use
As can be seen from the varieties of sealants, they all have a wide area of use. They can close cracks or holes in fireplaces, stoves. Seal the connections in the pumps. Such a sealant is widely used in car repair shops. Use it is recommended only according to the instructions. Its violation leads to the fact that the sealant will lose all its properties and characteristics. In the future, this will lead to the destruction of the connection, repeated repairs will be needed.
Sealant Features
High-temperature sealants are used not only in industry, but also at home. They help mend kitchen appliances and furniture. The main characteristics of such a material are:
- Heat resistance.
- Durability.
- Sealing and gluing materials.
High-temperature silicone sealant is available in the form of a paste, which is sealed in a long package. A special gun is used to squeeze out material for repair. It helps squeeze the sealant in small batches. Room temperature helps to quickly harden the material without losing elastic qualities.
Widespread sealant
High-temperature sealant has become an important repair material, without which it can be difficult to do in everyday life. The most common sealants are made on the basis of rubber and acrylic. They are also selected by color. Shades delight with their variety. Most often, high-temperature red sealant is found on sale. Bright color helps to see the sealant’s distribution area and smear empty elements with it.
Proper operation with high temperature sealant
Before using the sealant, you need to properly and thoroughly prepare the work surface. To do this, everyone is cleaned of dust and dirt. Washed with water and dried thoroughly. Then the surface is degreased with acetone. Insert a tube of sealant into the gun and cut off the tip. Gradually and carefully, apply sealant to the surface. The composition is leveled with a spatula and left to dry for a day. After that, the repaired part can be used for its intended purpose.
After many years, a high-temperature sealant appeared, which was widely used in everyday life and industry. With this relatively inexpensive material, all cracks can be fixed and joints improved.
