1. Treating fiberglass yarn with a sizing agent containing JH-41174 silane coupling agent (including film-forming agent, lubricant, and antistatic agent) can improve the mechanical strength of the fiberglass yarn reinforced composite material. 2. It can improve the dry and wet mechanical strength of polyester composite materials filled with silica, glass, silicate, and metal oxides. 3. It can improve the wet electrical properties of many inorganic filler filled composite materials. 4. It can be copolymerized with vinyl acetate and acrylic or methacrylate monomers to synthesize room temperature crosslinkable curing Silanized polymers. These silane based polymers are widely used in coatings, adhesives, and sealants. Provide excellent adhesion and durability.
