Tin-free silicone avoids conflicting chemistries and speeds assembly time

Wacker Elastosil N9111 available from Intertronics is a tin-free single part RTV silicone adhesive sealant, with neutral cure chemistry, offering a non-corrosive seal that does not inhibit other materials such as platinum cure silicones. This, along with its UL94 V-0 rating, makes it a strong candidate for electronics manufacturing, particularly for component ruggedisation, gap filling, and form-in-place gasketing. Elastosil N9111 is also well-suited for automotive and small appliance electronics, plus for new and sustainable energy devices or similar applications. Further applications for this general-purpose adhesive sealant comprise demanding bonding applications in the household appliances sector, such as screens and control panels in electric cookers, bonding of ceramic hobs, or mounting and bonding of front windows of microwave ovens. This new adhesive sealant is technically an alkoxy-curing RTV-1 system, formulated with a tin-free catalyst. This makes it ideal for applications in which organo-tin compounds act as inhibitors and are, therefore, undesirable, such as dam-and-fill applications. The adhesive offers significant time savings and processing advantages.
