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 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. The epoxy 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. Serviceable over the wide temperature range of -60°F to +450°F, EP62-1 has a shelf life of one year in unopened, original containers. It is available in an assortment of packaging options, including ½ pints, pints, quarts, gallons and 5 gallon kits. Specialty packaging also is available in gun kits, and premixed & frozen syringes.
