Elkem (Bluestar Silicones) CAF® 3 Silicone Rubber
Categories:	Polymer; Thermoset; Silicone; Silicone Rubber
Material Notes:	Description: CAF 3 is a one component, flowing silicone elastomer which cures at room temperature on contact with atmospheric humidity. The product is: Acetic. Flowing. Translucent. Applications: CAF 3 is mainly used in industrial sealing and bonding applications when requiring a flowing product. CAF 3 is notably used for: potting and insulation of electronic sensors, bonding of various materials, general maintenance in industry Advantages: CAF 3 is quick curing, has very good mechanical properties and good high temperature resistance. CAF 3 therefore provides perfect assembly and complete sealing between different materials subject to thermal stresses. CAF 3 also has good resistance to chemical agents.
