During the operation of heating systems and other various devices, cracks begin to appear. They need to be sealed only with special means 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 seal joints in automotive engines, pumps, transmissions, heating and ventilation systems. These sealants work well with the following materials:
- Glass.
- Enameled surface.
- Ceramics.
- Tree.
- Metal.
There are several main types of these sealants:
- High temperature sealant based on acetic silicone. They are used to seal seams and joints that are constantly under high temperature from 250 to 300 degrees. It is mainly used for industrial purposes. Absolutely not to be usedfor processing seams that are constantly in contact with gasoline. This sealant is available in three colors: black, red, beige.
- High temperature silicone based sealant. It is used for seams and joints that are at temperatures from -50 to +250 degrees. With constant temperature jumps, its properties do not change. used on many surfaces, even glass and metal.
- High temperature sealants based on one component. This type of material hardens from the humidity of the air. 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 from fiberglass. Apply sealant 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 the repair of gas equipment, central heating systems. Sealant on fiberglass becomes as hard as cement when it dries. Accordingly, he does not sit down and does not sit down. Can bond materials such as metal, brick, concrete.
- Elastic high-temperature sealants based on polyxylosan. Withstand temperatures up to +285 degrees. This sealant can replace cork, fiber, paper, asbestos or rubber. Produced consistency - red paste.
Using sealant
As can be seen from the varieties of sealants, they all have a wide area of use. They can be used to seal cracks or holes infireplaces, stoves. Seal connections on pumps. Such a sealant is widely used in car services for car repairs. It is recommended to use it 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, it will be necessary to re-repair.
Sealant Features
High-temperature sealants are used not only in industry, but also at home. They help fix kitchen appliances and furniture. The main characteristics of such material are:
- Heat resistant.
- Durability.
- Sealing and bonding materials.
High-temperature silicone sealant is produced in the form of a pasty mass, which is sealed in a long package. A special gun is used to extrude the repair material. It helps to squeeze out the sealant in small portions. Room temperature helps the material harden quickly without losing elasticity.
Sealant widespread
High temperature sealant has become an important repair material that can be difficult to do without 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 diversity. Most often, a high-temperature red sealant is found on sale. The bright color helps to see where the sealant is spreading and to apply it to empty elements.
Proper handling of high temperature sealant
Before using the sealant, you need to properly and thoroughly prepare the work surface. To do this, everything is cleaned of dust and dirt. Rinse with water and dry thoroughly. Next, the surface is degreased with acetone. Insert a tube of sealant into the gun and cut off the top. Gradually and carefully apply the 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 such a relatively inexpensive material, all cracks can be repaired and joints can be improved.
