Applications

• Mainly be used in unsaturated polyester composite material to improve the mechanical property, electric
• Imhibibition treatment (containing this coupling agent) to glass fiber, can improve the wet mechanica property and electric property of glass fiber reinforced composite material.
• In wire and cable industry, when used to treat EPDM system stuffed by pottery clay and crosslinked by peroxide, it can improve consumption factor and specific inductance captance.
• Polymerize with vinyl acetate and acrylic acid or methyl acrylic acid monomer. These polymers are widely used in coating, adhesive and sealing agent, providing excellent adhesion and durability.
