Material Coupling and Adhesion Promotion

• Silane coupling agents and adhesion promoters
• For chemically adhering closed textile structures or other difficult-to-adhere substrates
• Very good adhesion to glass fiber
• Useful for adhering acrylics, EPDM, epoxies, EVA, fiberglass, melamines, nitrile rubbers, nylons, PBT, PE, phenolics, polyester and unsaturated polyesters, polyolefins, polysulfides, PP, PVC, styrenics, urethanes
• For best adhesion to metal, post-cure at 150-200°C

Many silicones are designed to adhere well to a wide variety of substrates, but some silicone products and some surfaces require adhesion enhancement to achieve adequate bond strength. Surface treatments to improve adhesion can range from simple cleaning to more complex etching, and may require the application of reactive silane coupling agents to achieve optimal bonding.

Dow Corning® brand primers, prime coats and adhesion promoters are dilute solutions of silane coupling agents and other active ingredients. The surface reactive components typically must be applied in a very thin layer for best bonding. The solvents used in these products serve to deliver the active ingredients in a thin, uniform coating, enhance surface cleaning, and in some cases, aid in the penetration of the active ingredients into the bonding surface.
