FX219G5 – Silicone Potting & Encapsulation Compound
Everwide FX219G5 Silicone Potting Compound – high-thermal, UL94 V-0 silicone potting for electronic modules. Compare with Shin-Etsu KET-132 silicone potting.
Welcome to AVANTEK VIET NAM
1. Product Overview
LOCTITE STYCAST EE 4186 HD 3561 is a two-component epoxy system designed for encapsulation and potting applications. It features a low coefficient of thermal expansion (CTE), low shrinkage, and high impact strength, preventing microscopic cracking when flexible wire leads protrude from the encapsulation. The system adheres well to lead materials like vinyl and neoprene.
