High strength, two-component epoxy withstands elevated temperatures

With the ability to withstand acids, bases and many solvents, Master Bond EP62-1 is primarily used as an adhesive, sealant or coating where the epoxy will be exposed to very harsh conditions. This two part epoxy features thermal stability with a glass transition temperature exceeding 170°C.

EP62-1 has a long working life of over 12 hours at ambient temperatures and a forgiving 100 to 10 mix ratio by weight. This system features convenient colour coding to facilitate uniform mixing. The colour of Part A is clear and Part B is dark brown. It cures rapidly at moderately elevated temperatures, with schedules ranging from 4-6 hours at 60-70°C to 10 minutes at 125°C.

This lower viscosity system is a capable electrical insulator with a volume resistivity exceeding 1014 ohm-cm and a dielectric constant of 3.25 at 60Hz. EP62-1 delivers tensile shear strengths greater than 2,300psi and tensile strengths over 8,500psi. It is a dimensionally stable epoxy that contains no solvents.
