Application And Properties Of Amino Silanes Kh-550


Aminosilanes produced by KH-550 silane coupling agent is widely used in the following areas.

I. Coatings, adhesives, and sealants

The amino silanes is an excellent adhesion promoter and are used in acrylic coatings, adhesives, and sealants. For sulfides, polyurethanes, RTV, epoxy, nitriles, phenolic resins, adhesives and sealants, amino silanes can improve the dispersion of pigments and enhance the adhesion with glass, aluminum, and steel.

II. Reinforcement of Glass Fiber

Aminosilanes KH-550 can significantly improve the flexural strength, tensile strength and interlaminar shear strength under dry and wet conditions, as well as the wet electrical properties, when used in glass fiber reinforced thermosetting and thermoplastic plastics. The flexural strength and tensile strength of glass fiber reinforced thermoplastics, polyamides, polyesters, and polycarbonates increased before and after immersion when amino silanes were used in dry and wet conditions.

III. Glass Fiber and Mineral Cotton Insulation Material

Adding it to phenolic resin adhesives can improve the moisture resistance and resilience after compression.

IV. Mineral fillers and resin systems

The amino silanes can greatly improve the physical, mechanical and electrical properties of phenolic resin, polyester resin, epoxy, polyamine, polycarbonate and other thermoplastic and thermosetting resins filled with inorganic fillers, and improve the wettability and dispersion of fillers in polymers.

V. Casting Application

The use of amino silanes can reduce the amount of phenolic resin or furan resin bonding agent used in silicon sand casting mold, increase the strength of sand and reduce the gas emission.

VI. Manufacture of Resin Grinding Wheels

The amino silanes help to improve the adhesion and water resistance of abrasion-resistant self-hardening sand and phenolic adhesives.

VII. Application of Wood Plastics Manufacturing

The amino silanes can improve the impact strength, flexural strength, flexural modulus and other mechanical properties of wood flour treated composites.
