1.Performance and use:
Colourless transparent liquid, easily soluble in a variety of solvents, insoluble polysiloxane is formed after hydrolysis and curing. Uses are mainly used to improve the bonding properties of organic and inorganic materials on the surface, such as glass fibre in glass fibre reinforced plastic and plastics, rubber, paints, coatings and other materials such as silica filler treatment, also used in adhesives to increase adhesive properties, it is adapted to the resin including epoxy, phenolic, melamine, polysulphide urethanes, polystyrene and so on.
1. It is mainly used in unsaturated polyester composite materials, which can improve the mechanical properties, electrical properties and light transmission properties of composite materials, especially it can greatly improve the wet state properties of composite materials.
2. Wet treatment of glass fibre with (containing the coupling agent) can improve the mechanical strength and electrical properties of glass fibre reinforced composites in wet state.
3. In the wire and cable industry, the coupling agent is used to treat clay-filled peroxide crosslinked EPDM system, which improves the consumption factor and specific inductance resistance.
4. Copolymerised with vinyl acetate and acrylic or methacrylic monomers, these polymers are widely used in coatings, adhesives and sealants to provide excellent adhesion and durability.
Coupling of the two materials to improve the mechanical strength of the product, the electrical properties of the composite material, weathering and corrosion resistance, applicable to unsaturated polyester, acrylate adhesives
