N-Hexyltrimethoxysilane CAS No:3069-19-0 C9H22O3Si

Main Applications

1.‌Engineering Plastic Modification‌: Used in fiber-reinforced or filled systems such as nylon and PBT to significantly improve mechanical strength.

2.‌Epoxy Resin Reinforcement‌: Treats inorganic fillers such as silica microspheres for use in epoxy molding compounds, mortars, and molds to enhance interfacial adhesion.

3.‌Sealant Replacement Component‌: Replaces mercaptosilanes in construction and glass polysulfide sealants, providing excellent tack-enhancing effects without odor.

4.‌Adhesive Tack Enhancer‌: Added to polyurethane and latex-based adhesives to improve bonding strength; does not yellow and does not affect shelf life.

5.‌Waterproofing of Building Materials‌: Acts as a low-VOC waterproofing agent that penetrates concrete and cement-based substrates to form a protective film, enhancing resistance to alkali and de-icing salt corrosion.‌‌

Storage Instructions

1.‌Environmental Requirements‌: Store in a tightly sealed container in a cool, dry, and well-ventilated area, away from direct sunlight; some high-purity grades are recommended for refrigerated storage at 0–6°C, while industrial-grade products typically require storage at temperatures ≤30°C.

2.‌Key to Moisture Protection‌: Strictly prevent moisture ingress; exposure to moisture can cause hydrolysis and polycondensation, forming polymers that lead to product failure.
