Silicone Primer for use with One and Two-Component RTV Silicone Adhesive Sealants.

SS4179 primer is formulated for use with GE Silicones RTV silicone rubber adhesive sealants. GE Silicones one-component products offer primer less adhesion to many substrates. Primer is 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). SS 4179 is a one-component product requiring no mixing and is supplied ready-to-use as easily pourable solvent solutions.

SS4179 primer helps promote adhesion of GE Silicones sealant to difficult-to-bond plastic substrates including:

• acrylics
• acrylonitrile-butadiene-styrene (ABS)
• cellulosic (cellulose acetate)
• high-impact styrene
• polyphenylene oxide resins (PPO)
• polysulfones
• polyesters
• rigid polyvinychloride (PVC)
• thermoplastic resins (Noryl)
