Resinlab® EP1282 Clear Unfilled Electronic Grade Epoxy Encapsulant

Resinlab™ EP1282 Clear is a two part unfilled electronic grade epoxy encapsulant designed for medium sized castings. It is recognized under the Component Recognition Program of Underwriters Laboratories Inc., (File# E186034) for UL Standard 94. It qualifies for a horizontal burn rating at 1.5 mm thickness and has a CTI rating of 0. The system cures at room temperature to a tough, semi-rigid polymer. It has good wetting and adhesion to most surfaces and is free flowing to penetrate voids and give good air release and a smooth high gloss surface. It has very good resistance to water, acids and bases and most organic solvents. Thermal shock and cycling properties are enhanced by its high elongation giving it the ability to absorb differences in CTE’s of substrates and potted components. 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. EP1282 Clear will reach full cure at room temperature within 24 – 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 20 minutes at 100°C are typical for small castings (less than 50 grams).Information Provided by Resinlab L.L.C., an Ellsworth Adhesives Company.
