Chemically Resistant adhesives

Cookson Group Plaskon® 1031 Conventional Encapsulant  (discontinued **)
Categories: Polymer; Thermoset; Epoxy; Epoxy Encapsulant, Unreinforced
Material Notes: Test specimens were transfer molded and post cured 4 hours at 175°C.

A low cost, conventional molding compound recommended for high volume commodity-type packages that house simple linear and discrete devices. These packages include low lead count DIPs, TO-types, diodes and small SOICs. Excellent moldability (fast curing, minimal if any deflashing, no degreasing); Superior cosmetics and markability
