DOW DOWSIL Z-2306 Silane

DOW DOWSIL Z-2306 Silane is a specialty amino-functional silane coupling agent from Dow’s DOWSIL™ portfolio. It enhances adhesion between organic polymers and inorganic substrates like glass, metals, or minerals. Widely used in sealants, adhesives, coatings, and composites, it improves mechanical strength, moisture resistance, and durability. Its reactive amine group bonds with resins while alkoxy groups hydrolyze to anchor onto surfaces.
