An Introduction to Silane coupling agent KH-558
Silane coupling agent KH-558 is an amino-group silicone, alkaline. It is a colourless or light yellow transparent liquid, versatility, it can be dissolved in an organic solvent, acetone, carbon tetrachloride but not suitable for thinner. Soluble in water, hydrolyzed in water, the boiling point 217 c.
Silane coupling agent KH-558 molecule contains two different types of active group--p-and oxygen radicals, for coupling of organic polymers and inorganic fillers, enhance its cohesiveness, improve product of mechanical, electrical, water resistance, aging resistance and other properties. It is often used in glass, foundry, textile auxiliary, insulating materials, adhesives and other industries.
1. Silane coupling agent KH-558 applied to mineral-filled phenolic, polyester, epoxies, PBT, poly phenolic amine, polycarbonate, thermoplastic and thermosetting resin, can greatly improve the dry-wet-resistant of reinforced plastic bending strength, physical and mechanical properties such as compressive strength, shear strength and electrical properties of wet and improved wetting and dispersion of fillers in polymers.
2. Silane coupling agent KH-558 is excellent adhesion promoter, can be used in polyurethane, epoxy, nitriles, phenolic resin adhesive and sealing material, improved pigment dispersion and improve on glass, aluminum, ferrous metal adhesive, apply polyurethane, epoxy and acrylic latex paint.
3. Resin sand casting, Silane coupling agent KH-558 reinforced silicone resin adhesion, improving the strength and resistance to wetting.
4. In the production of glass wool and mineral wool, its phenolic adhesive, to improve moisture resistance and compression elasticity.
5. In wheel manufacturing, it helps to improve the wear-self-hardening sand amount of phenol-formaldehyde resin adhesive bonding and resistance.
