  1. Mainly used in unsaturated polyester composite materials, which can improve the mechanical properties, electrical properties, and light transmission properties of the composite materials, especially the wet performance of the composite materials.
  2. Use (containing the coupling agent) to infiltrate the glass fiber to improve the wet mechanical strength and electrical properties of the glass fiber reinforced composite material.
  3. 3 In the wire and cable industry, using this coupling agent to treat the ceramic clay filled with peroxide cross-linked EPDM system improves the consumption factor and specific inductance and capacitive reactance.
  4. Copolymerized with vinyl acetate and acrylic or methacrylic monomers. These polymers are widely used in coatings, adhesives and sealants to provide excellent adhesion and durability.
