Silicone Primer SS4044P

SS4044P 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.

SS4044P primer helps promote adhesion to metals (such as aluminum, copper, steel, stainless steel, brass, and galvanized metals), porous materials, unglazed ceramics and wood. SS4044P primer is virtually identical to SS4004P primer, but is designed for applications where discoloration of the substrate is undesirable.
