Two primerless encapsulants from Dow Corning should bring greater adhesion and stress relief to electronic applications, along with a fast, room-temperature cure. Both deliver an uncharacteristic toughness and peel strength for a silicone dielectric gel material, the company reports. Dow Corning(reg) 3-4220 Firm Gel is one part blue and one yellow, facilitating visual inspection for complete mixing. Dow Corning 3-4219 Firm Gel, a clear version, contains no dye or UV indicator, and is designed to help prevent radio-frequency interference in applications involving wireless communications.
