High-Temperature Sealant Series
High–Temperature Sealant series are polymeric patching materials of ceramics and metal. With excellent high temperature resistant performance, it is used for settle different works like sealing, filling, potting, splicing that regular adhesive could not be done.
DB737 High-Temperature Healant
Packing: 250g / set
Two constituent, plaster, fill by metal and ceramics, high-temperature resistance, anti-friction. Long-period temperature resistance: 230℃. Instantly temperature resistance: 280℃, use for repairing abrasion, scratch, corrosion of device in high-temperature: such as steam or hot oil pipe leaking, corrosion and scratch on engine, rusty edge of paper dryer and leakage end cap, fixing of plastic mould.
DB757 High-Temperature Sealant
Packing: 500g / set
Two constituents, high-temperature resistant and well sealability, durable working under 350℃, use for sealing and fixing oil, air, acid, alkali device and junction surface of wire under high-temperature, especially for the sealing of junction surface of steam turbine.
DB767 High-Temperature Sealant
Packing: 250g / set
