SK-PR921
Product Introduction:
SK-PR921 is a single-component silane and silicone resin-modified primer designed to enhance adhesion between addition-cure silicone rubber and substrates such as metal, PA (nylon), PC, PET, and PCBA. It forms a chemical bonding interface layer, significantly improving bond strength and weather resistance. Key features include a wide processing window and excellent hydrolysis stability.
