Product Information

SS4004P, SS4044P, SS4120, SS4155, and SS4179 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. SS4004P and SS4044P primers help promote adhesion to metals (such as aluminum, copper, steel, stainless steel, brass, and galvanized metals), porous materials, unglazed ceramics and wood. SS4004P primer is bright pink, providing easy visual determination of uniform coating.

SS4044P primer is virtually identical to SS4004P primer, but is designed for applications where discoloration of the substrate is undesirable. SS4120 primer helps promote adhesion of Momentive Performance Materials addition cure RTVs and is used where clarity is needed. SS4155 is a general purpose primer for use with any RTV.


  • One-component - no mixing
  • Simple handling procedures and equipment for easy use and low processing cost.

  • Cellulosics (cellulose acetate)
  • High-impact styrene
