Heat Resistant Sealants
Sealants are materials that close the gaps between solid sections of a machine so that they better resist high temperature and pressure. They are present in two forms, liquid foam and cement. Liquid foam sealant is used to seal machined connections and threading. Through this material you can achieve close tolerance to sealing. Cement sealants are primarily used to cover rough surfaces.
Sealants can effectively resist temperatures between 315°F and 1500°F (157°C to 816°C). They can also utilize some heat to cure the seal properly within a very short period of time. They are used in precise works due to their low shrinkage and expansion coefficient. Seals made by these materials can also resist unwanted chemicals such as hydrocarbons, ammonia, brine, acids, and mild alkalis. They significantly reduce damage due to vibration and shock as well.
Sealants are used where very precise and strong sealing is required. Due to their tremendous properties, they are used in industries like power generation, heavy equipment, automotive, oil, steel chemical, marine, and more. They are used to repair leaks present in boilers, steam turbines, refrigeration lines, compressors, pressure vessels, heat exchangers, condensers, and other hydraulic and thermodynamic systems.
