Tough Gels Overview

Features
Firm or tough, thermal/mechanical shock and vibration damping, primerless chemical adhesion at room temperature (except 3-4237 Dielectric Firm Gel which requires heat to develop chemical adhesion), excellent dielectric properties, flexible cure schedule, reversion resistant, thick section cure, compatible with automated dispensing equipment, and physical and electrical stability over a wide temperature range (-45 to 150°C/-49 to 302°F)

Potential Uses
Sealing and protecting, by coating, encapsulating, or potting, various electronic devices, especially those with a need for stronger adhesion or improved dimensional stability; 3-4237 Dielectric Firm Gel, with its exceptionally long working time, is especially suited for penetrating intricate parts
