Single Component Silicone Primer

SS4000 Series primers are 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.

• One-component - no mixing
• Simple handling procedures and equipment for easy use and low processing cost.
• Dry at room temperature and ambient humidity conditions
• Helps promote adhesion to many substrates
• SS4120 primer is transparent to preserve the visibility of colorless products.
• Pink color of SS4004P and blue color of SS4155 primer permit easy visual determination of uniform application.
