Momentive SS4004P Pink Primer

SS4004P, SS4044P, SS4120, SS4155, and SS4179 primers are formulated for use with MomentivePerformance Materials RTV silicone rubber adhesive sealants. Momentive Performance Materialsone-component products offer primerless adhesion to many substrates.

Primers are used to help promoteadhesion to difficult-to-bond substrates. For most Momentive Performance Materials two-componentproducts, a primer is required when an adhesive bond is needed between the silicone rubber compoundand a non-silicone surface (see table below). All primers are one-component products requiring no mixingand 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 virtuallyidentical to SS4004P primer, but is designed for applications where discoloration of the substrate isundesirable.SS4120 primer helps promote adhesion of Momentive Performance Materials addition cure RTVs and isused where clarity is needed. SS4155 is a general purpose primer for use with any RTV.

Features:

• 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 SS4044P, SS4120 and SS4179 primers are transparent to preserve visibility of colorless products.
• Improve adhesion of 2 part silicones
• Pink color of SS4004P and blue color of SS4155 primer permit easy visual determination of uniform application.

SS4179 primer helps promote adhesion of Momentive Performance Materials sealant to difficult-to-bond plastic substrates including:

• Acrylics
• Acrylonitrile-butadiene-styrene (ABS)
• Cellulosics (cellulose acetate)
• High-impact styrene
• Polyphenylene oxide resins (PPO)
• Polysulfones
• Polyesters
• Rigid polyvinychloride (PVC)
