Application performance

Aminosilane produced by KH-550 silane coupling agent is widely used in the following range.

(1) Reinforcement of glass fiber

When used in glass fiber reinforced thermosetting and thermoplastic plastics, aminosilane KH-550 can significantly improve the bending strength, tensile strength, and interlayer shear strength in dry and wet states, and significantly improve the wet electrical performance. When using this silane in both dry and wet conditions, the flexural and tensile strength of glass fiber reinforced thermoplastic plastics, polyamides, polyesters, and polycarbonates all increase before and after immersion.

(2) Coatings, adhesives, and sealants

This aminosilane is an excellent adhesive promoter used in acrylic coatings, adhesives, and sealants. For sulfides, polyurethane, RTV, epoxy, nitrile, phenolic resins, adhesives, and sealants, aminosilane can improve the dispersion of pigments and enhance the adhesion with glass, aluminum, and steel.

(3) Glass fiber and mineral surface insulation materials

Adding it to phenolic resin adhesive can improve moisture resistance and rebound after compression.

(4) Mineral fillers and resin systems

This product can significantly improve the physical, mechanical, and electrical properties of thermoplastic and thermosetting resins such as phenolic resin, polyester resin, epoxy, polyamine, and polycarbonate filled with inorganic fillers, and improve the wettability and dispersibility of fillers in polymers.

(5) Foundry applications

This product can improve the adhesion between phenolic adhesives and casting sand. Grinding wheel manufacturing

This product helps to improve the adhesion and water resistance of wear-resistant self hardening sand and phenolic adhesive.
