3-Aminopropyltrimethoxysilane

Product details

Amino and methoxy groups are used to couple organic polymers and inorganic fillers respectively to enhance their adhesion and improve the mechanical, electrical, water resistance, anti-aging and other properties of the product. 

Used in mineral filled thermoplastic and thermosetting resins such as phenolic, polyester, epoxy, PBT, polyamide, carbonate, etc., can greatly improve the dry and wet flexural strength, compressive strength, shear strength and other physical mechanics properties and wet electrical properties of plastics, and improve the wettability and dispersion of fillers in polymers. In resin sand casting, it enhances the adhesion of resin silica sand and improves the strength and moisture resistance of molding sand. In the production of fiberglass wool and mineral wool, adding it to the phenolic binder can improve moisture resistance and increase compressive resilience.

Excellent adhesion accelerator, can be used in polyurethane, epoxy, nitrile, phenolic adhesives and sealing materials to improve the dispersion of pigments and improve the adhesion to glass, aluminum and iron metals. It is also suitable for polyurethane, epoxy and acrylic latex coatings.

Used in the synthesis of amino silicone oil and its emulsion.
