Momentive™ SS4120 Clear Adhesive Primer - Pint Bottle

SS4120 primer is formulated for use with Momentive Performance Materials RTV silicone rubber adhesive sealants.  Momentive Performance Materials one-component products offer primerless adhesion to many substrates.  Primers are used to help 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 (see table below).  All primers are one-component products requiring 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 where clarity is needed.
