High Temperature Resistant Bonding, Sealing and Coating CompoundsMaster Bond features an extensive line of heat resistant adhesives, sealants, coatings and potting/encapsulation compounds that can withstand temperatures as severe as 600°F and higher. Our epoxy systems are presently employed on satellites, downhole oil equipment, medical devices, automotive components, lasers and other equipment applications.

High Temperature Resistant Compounds

Our heat resistant product line includes one and two component:

  • Epoxies
  • Silicones
  • Urethanes

Performance Properties for High Temperature Resistant Adhesives

As with all products in the Master Bond family, specific grades vary in viscosity, cure speed, chemical resistance and electrical properties, but can be customized to meet your application needs.
