Shin-Etsu KE-40RTV Flame-Retardant RTV Silicone Adhesive Sealant
KE-40RTV is a one-component, room-temperature vulcanizing silicone adhesive sealant developed by Shin-Etsu Chemical Co., Ltd. It features a neutral condensation cure system, thixotropic consistency, low odor, and non-corrosive properties. The product provides good adhesion to metals, plastics, glass, and ceramics without primer. After curing, it forms a tough and durable elastomer with UL 94 V-0 flame retardancy, making it suitable for electronic sealing, industrial bonding, and form-in-place gasketing.
