Material Notes:
SS4004P, SS4044P, SS4120, SS4155, and SS4179 primers are formulated for use with GE Silicones RTV silicone rubber adhesive sealants. GE Silicones one-component products offer primerless adhesion to many substrates. Primers are used to help promote adhesion to difficult-to-bond substrates. For most GE Silicones 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.Recommended for 1 and 2 part condensation RTVs.Key Performance Properties: One-component - no mixingSimple handling procedures and equipment for easy use and low processing cost.Dry at room temperature and ambient humidity conditionsHelps promote adhesion to many substratesPink color of SS4004P primer permits easy visual determination of uniform applicationGE Silicones became a part of Momentive Performance Materials in 2006.
