Low Corrosion
Low Odour
General purpose sealing, bonding and gasketing

Shin-Etsu KE-45 RTV adhesive/sealant is a paste-like, one-component material that cures to a durable, resilient silicone rubber when exposed to moisture in the air at room temperature. Due to its non-sag, non-flowable features it may be applied overhead or on side wall joints and surfaces. It will adhere to glass, most types of wood, clean metals, silicone resins, ceramics, vulcanized silicone rubber, natural and synthetic fibres, and many plastic surfaces. KE 45 RTV can be used for general sealing as well as electrical insulation. It presents no offensive odour during curing and will not corrode metal. (Discolouration of copper based metals may occur when hermetically sealed.) In addition, KE 45 RTV Silicone adheres well on alkali materials such as mortar and white cement.
