ShinEtsu KE-445 One-Component RTV Sealant - Elastic Solution for Electronics

Product Overview

Shin-Etsu KE-445 is a one-component, room-temperature vulcanizing (RTV), self-leveling silicone sealant that cures into a flexible and durable elastomer. Featuring a neutral cure system, it is non-corrosive, low-odor, and provides excellent adhesion to metals, plastics, glass, and ceramics without requiring a primer.
