Isooctyltrimethoxysilane CAS No:34396-03-7 C11H26O3Si

Main Applications

1.coupling agents‌: Improve the adhesion at the interface between inorganic fillers (glass, minerals, silica, etc.) and organic polymers (rubber, plastics, resins), enhancing the mechanical properties and weather resistance of composite materials.

2.waterproofing and seepage prevention‌: Used in the surface treatment of cement-based materials and natural stone, as well as in concrete additives, to significantly improve impermeability and water resistance.

3.Surface Modification‌: Used for treating powders such as titanium dioxide and wear-resistant carbon black to enhance dispersibility and compatibility (e.g., when used in conjunction with silica in rubber).

4.‌Additives for Coatings/Adhesives/Sealants‌: Serves as an adhesion promoter and hydrophobic modifier in applications such as coatings, adhesives, sealants, and electronic encapsulation materials.

5.‌Chemical Intermediates‌: Serves as a raw material for synthesizing other functional organosilicon compounds.‌‌

Storage Instructions

1.‌Environmental Requirements‌: Store in a cool, dry, and well-ventilated area, away from direct sunlight; room temperature storage is recommended.

2.‌Seal to Prevent Moisture‌: Keep containers tightly sealed to prevent hydrolysis caused by contact with moisture in the air; reseal immediately after use.

3.‌Safety Precautions‌: Keep away from sources of ignition and heat; open flames are strictly prohibited. Store separately from water, strong acids, and strong oxidizing agents; do not store or use together.
