It is a high-temperature resistant silicone rubber that can continuously withstand temperatures from -62°C to +343°C without affecting performance. It remains elastic even at high temperatures and possesses excellent adhesion properties, high electrical insulation, reliable waterproofing, resistance to grease and vibration, and high aging resistance. This high-temperature adhesive can resist various corrosive chemical agents and provides strong adhesion to metals, plastics, wood, glass, ceramics, fiberglass cloth, and other materials under temperature variations. It can be formed on-site into high-temperature resistant sealing gaskets of any size and shape as needed for the bonding surface, thereby achieving special functions such as bonding, leak sealing, fastening, insulation, and sealing.
