How Do I Choose the Best Heat-Resistant Glue?

With a temperature resistance of 1500 ° C or higher, and a thermal conductivity of 0.06w / m · k, it can be used as coating materials for ceramics, glass, and metals. Sprayed on the surface of metal, quartz and other objects, low temperature drying, very good adhesion, hard, no cracking, no foam, high temperature resistance of 1500 degrees, can be used on iron, steel, quartz, ceramics, glass and other surfaces.

High temperature resistant glue

To withstand temperatures of 1500 ° C and higher,

The glue can withstand temperatures of 1500 ° C and higher, with a thermal conductivity of 0.06w / m · k. It can be used as a ceramic,

High temperature glue can be divided into organic by nature

Single-component sealed high temperature adhesive

Below 250 , various modified high-temperature epoxy adhesives are mainly used. 250 to 400 is mainly silicone resin adhesives. In general, inorganic adhesives are used when the temperature exceeds 400 .

Inorganic high-temperature adhesive brittle, generally have low peel strength and high shear strength. Generally used for bonding or fixing refractory bricks, asbestos, ceramics or these materials with carbon steel. The typical model is that the effects are good, and the inorganic high-temperature glue cured product specially used on high-temperature lamp holders is similar to ceramics and is widely used in lamp factories.
