γ-aminopropylmethyl diethoxysilane KH-902

Introduction:

KH-902 silane coupling agent, γ-aminopropylmethyl diethoxysilane, is a general amino functional silane coupling agent, widely used to promote the adhesion of inorganic substrates and organic substances, forming inorganic Strong bonding between substrate and organic polymer.

Product description: The silicon-containing part of the product molecule has strong adhesion to the substrate. The primary amine functional group interacts with a series of thermosetting resins, thermoplastic resins and rubber materials. Its molecular formula is as follows: H₂NCH₂CH₂CH₂SiCH₃(OCH₂CH₃)₂

Typical physical characteristics:

Exterior	Colorless transparent liquid
Refractive index	1.4260-1.4290
Density (ρ20 )g/cm 3	0.911-0.917
content%,	97.0

Solubility: KH-902 silane coupling agent can be completely and easily soluble in water (chemical reaction), ethanol, aromatic hydrocarbons and aliphatic hydrocarbons. It is best not to use copper as a thinner.

Coatings, adhesives and sealing: The aminosilane can be used as an excellent adhesion promoter for acrylic coatings, adhesives and sealants. When used in polysulfide, polyurethane, RTV silicone resin, epoxy, nitrile and phenolic adhesives and sealants, it can improve the dispersion of pigments and tightly bond with glass, aluminum and steel.

Glass-reinforced resin system: In glass-reinforced thermosetting resin, KH-902 silane coupling agent can enhance the bending strength, impact strength and tensile strength of the resin in moisture. At the same time, it is the same for glass exposed to moisture in reinforced thermosetting plastic, polyamide, polyester and polycarbonate.

Fiber and mineral fabric insulation material: As a phenolic resin bonding additive, KH-902 silane coupling agent improves moisture resistance and resilience after compression.

Mineral-filled resin system: KH-902 silane greatly improves the physical and electrical properties of mineral-filled phenolic plastics, epoxy, polyamide, dibutyl polyphthalate, and many other thermosetting resins and thermoplastics. It can also improve the filler wettability and dispersibility in the polymer matrix.
