MG Chemicals SS4120-1P Transparent Silicone Primer

SS4120 Primer is formulated for use with Momentive Performance Materials’ RTV silicone rubber adhesive sealants. Momentive Performance Materials’ one-component products allow primerless adhesion to many substrates. Primers are used to promote adhesion to difficult-to-bond substrates. For most Momentive Performance Materials two-component products, a primer is required when an adhesive bond is needed between the silicone rubber compound and a non-silicone surface.

All primers are one-component products that require no mixing, and are supplied ready-to-use as easily pourable solvent solutions.

SS4120 Primer helps promote adhesion of Momentive Performance Materials’ addition cure RTVs and is used when a clear medium is required.
