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 12 hours at ambient
temperatures and a 100 to 10 mix
ratio by weight. This system features convenient
color coding to facilitate uniform
mixing. The color 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 60 Hz. EP62-
1 delivers tensile shear strengths greater
than 2,300 psi and tensile strengths over
8,500 psi. It is a dimensionally stable epoxy
that contains no solvents or diluents
