Description
Dow 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. Primers can be used to increase design flexibility, reduce total costs or increase performance reliability of PCB system assemblies. They do this by enabling adhesion to lower-cost substrates or lower temperature processes which reduce energy budgets, among other possibilities.
• Useful for both moisture curing RTV and heat curing silicones
• Diluted in low molecular weight silicone fluid
• Meets many international regulations for low VOC content (including European Union)
• Similar to DOWSIL™ P5200 Adhesion Promoter
• Useful on most metals, glass, ceramics, masonry, wood, fabric and some plastics (including FR-4)
Typical applications for DOWSIL™ 1200 OS Primer: enhance bonding/adhesion of RTV and heat cure silicones to many metals, ceramics, glass, wood, masonry, structural plastics
Available in pints (16 oz can)
