Material Notes:
Resinlab™ EP1121 Clear is a two part unfilled electronic grade epoxy encapsulant designed for small to medium sized castings. It cures completely at room temperature to a tough, flexible polymer. Its low viscosity allows for good wicking and penetration into components and circuitry and also gives good air release. It has very good resistance to water, acids and bases and most organic solvents. Thermal shock and cycling properties are also enhanced by its high elongation giving it the ability to absorb difference in CTE's of substrates. It was especially formulated to a 1A:1B volume mix ratio for use in side-by-side dispensing cartridges and meter/mix and dispense equipment. EP1121 Clear will reach full cure at room temperature within 24 to 48 hours. Cure time can be accelerated by the application of heat after product has gelled. Times and temperatures from 1 hour at 65°C to 10 minutes at 100°C are typical for small castings (less than 50 grams).Information Provided by Resinlab L.L.C., an Ellsworth Adhesives Company.
