Prime and prepare your aircraft's surfaces to accept a rubber adhesive sealant by pre-treating them with Momentive SS-4004 Adhesive Sealant Primer from SkyGeek. The one-part primer solution is formulated for use with Momentive Performance Materials RTV silicone rubber adhesive sealants. Use the primer to clean and prepare surfaces prior to using adhesive products. A clean, well-prepared surface better accepts adhesives and allows for a stronger, long-lasting hold. Momentive Performance Materials one-component products offer primerless adhesion to many substrates, including 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.
Momentive SS-4004 Primer from SkyGeek helps promote adhesion to metals (such as aluminum, copper, steel, stainless steel, brass, and galvanized metals), porous materials, unglazed ceramics and wood. The liquid formula is bright pink, providing easy visual identification as well as making it easy to tell if you've applied a uniform coating. SS-4044P Primer is specially designed for applications where discoloration of the substrate is undesirable. Once poured onto the surface, the premium primer goes on easily and spreads well, quickly preparing the surface to accept an adhesive.
SkyGeek carries Momentive SS-4004 Sealant Primer in convenient pint-size bottles. The primer is priced affordably and quantity discounts are available on bulk orders. Choose Momentive SS4004P Sealant Primer to improve adhesion on non-silicone surfaces throughout your aircraft. Once finished, the bottle is resealable for convenience and improved storage capabilities. Add a manufacturer’s certification to your order for a small additional charge.
