High-temperature sealants: features and characteristics of the material for repair

During operation of heating systems and othervarious devices begin to appear cracks. Seal them only need special means that are able to withstand high temperatures. Such materials include a high-temperature sealant. Let's consider all its features and characteristics.

What is a sealant. Types of high-temperature sealants

High-temperature sealants are definedThe kind of sealants that are treated with seams in automobile engines, pumps, gearboxes, in heating and ventilation systems. These sealants are well combined with the following materials:

• Glass.
• Enamelled surface.
• Ceramics.
• Tree.
• Metal.

There are several main types of such sealants:

1. High-temperature sealant based onacetic acid silicone. Apply for sealing joints and joints, which are constantly under a high temperature of 250 to 300 degrees. It is mainly used for industrial purposes. Categorically can not be used for the treatment of joints, which are constantly in contact with gasoline. This sealant is available in three colors: black, red, beige.
2. High-temperature sealant based on silicone. It is used for seams and joints, which are at a temperature of -50 to +250 degrees. At constant temperature jumps, its properties do not change. It is used with many surfaces, even with glass and metal.
3. High-temperature sealants on a one-componentbasis. This kind of material hardens from the humidity of the air. Use it at a temperature of -65 to +300 degrees. Sealant is used to repair metal parts, pumps and kitchen equipment.
4. Sealant for fireplaces. It is made of fiberglass. Apply a sealant for the repair of fireplaces, stoves, fireboxes and chimneys. You can also apply to repair the exhaust system of cars and motorcycles. It is strictly forbidden to use gas equipment, central heating systems for repair. The sealant on the fiberglass after drying becomes hard, like cement. Accordingly, he does not sit down or sit down. You can attach materials such as metal, brick, concrete.
5. Elastic high-temperature sealants forbased polysiloxane. Withstand the temperature to +285 degrees. Such a sealant can replace the plug, fiber, paper, asbestos or rubber. The consistency is a paste of red color.

Use of sealant

As seen from the varieties of sealants, they are allhave a wide area of ​​use. They can close cracks or holes in fireplaces, stoves. Seal connections in pumps. This sealant is widely used in car repair shops for car repairs. 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, you will need a second repair.

Features of sealant

High-temperature sealants are used not only in industry, but also at home. They help to repair kitchen appliances and furniture. The main characteristics of this material are:

• Heat resistance.
• Durability.
• Sealing and bonding of materials.

Silicone high temperature sealantIt is produced in the form of pasty mass, which is sealed in a long package. To extrude the material for repair, a special gun is used. It helps to squeeze out sealant in small portions. Room temperature helps quickly harden the material without losing the elastic qualities.

Wide spread of sealant

High-temperature sealant has become importantrepair material, without which it is difficult to do in everyday life. The most common sealants are based on rubber and acrylic. They are also chosen according to their color. Shades delight in their diversity. Most often, high-temperature red sealant is on sale. A bright color helps to see the area of ​​spreading sealant and smudge them with empty elements.

Correct work with high-temperature sealant

Before using the sealant,carefully prepare the work surface. For this, everything is cleaned of dust and dirt. Rinse with water and thoroughly dry. Then degrease the surface with acetone. Insert the tube with sealant into the gun and cut off the tip. Gradually and accurately you need to apply sealant to the surface. Composition is leveled with a spatula and allowed to dry for a day. After that, the repaired part can be used for its intended purpose.

After many years appearedHigh-temperature sealant, which was widely used in everyday life and industry. With such a relatively inexpensive material, you can repair all cracks and improve connections.
