Low corrosion
Excellent adhesion to many substrates
Low odour

Shin-Etsu KE-44 silicone is a versatile one-component, ready to use, low corrosoion adhesive/sealant. It cures to a tough, durable, resoilient silicon rubber on exposure to atmospheric moisture at room temperature.

KE-44 adhesive/sealant is used in a variety of applications as glue and anchoring sealants for electrical and electronic parts. It adheres to most surfaces including glass, wood, ceramics, clean metals, sislicone resins, vulcanized silicone rubber, natural and synthetic fibres, and many plastic surfaces. With its oxime neutral curing system, this adhesive/sealant presents no offensive odour during curing and will not corrode meatal. (Discolouration of copper based metals may occur when hermetically sealed.) KE44 is a medium to high viscocity liquid ideal for flow coating
