Silicone Primer, Prime Coats, Adhesion Promotors
DOW Silicones (formerly Dow Corning) delivers a wide variety of silicone-based polymers for diverse solutions in electric, electronic and energy applications. DOWSIL™ primers, prime coats, and adhesion promoters offer a variety of benefits to users. Robust adhesion maximises reliability and offers protection across a wider range of environmental conditions. The range of device design options may be expanded by enabling adhesion or providing lower temperature adhesion to a wider variety of substrate materials. Low-temperature or room-temperature adhesion may also reduce energy or capital costs or increase manufacturing flexibility.
Many of the DOWSIL™ silicones we offer 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.
Silane-based 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.
