Name: Dow SYLGARD 527 A&B Silicone Adhesive
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Dow SYLGARD 527 A&B Silicone Adhesive

Two-part, platinum-cured silicone system offering excellent flexibility and long-term reliability after cure.
Low modulus and high elongation (>100%) enable stress relief in bonded assemblies subject to thermal cycling or mechanical vibration.
Excellent adhesion to a broad range of substrates including glass, metals, ceramics, and many plastics without primers.
UL 94 V-0 rated for flame resistance, supporting safety-critical electronic encapsulation and potting applications.
Low viscosity before mixing (Part A ~15,000 cP; Part B ~50 cP) enables easy dispensing and thorough wetting of complex geometries.

Typical Applications Of Dow SYLGARD 527 A&B Silicone Adhesive

Encapsulation and potting of power electronics, including IGBT modules and LED drivers.
Bonding and sealing of sensors, automotive control units, and under-hood components exposed to wide temperature swings.
Die-attach and conformal coating for high-voltage and high-reliability aerospace and defense electronics.
Flexible interconnect bonding in wearable medical devices requiring biocompatibility-compliant materials.
