CATEGORY

3-Thiocyanatopropyltriethoxysilane is a sulfur-containing, bifunctional organosilane coupling agent widely used in various fields, such as rubber and coatings. Its molecular structure features a thiocyanato group (-SCN) linked to a silicon atom via a propyl chain (CH2CH2CH2-), with the silicon atom further bonded to three ethoxy groups (-OCH3). The silane group forms covalent bonds with the surface of inorganic materials (typically through hydrolysis), while the thiocyanato moiety can interact with organic materials.

Function

Used as a silane coupling agent to enhance the abrasion resistance, elasticity, and tear strength of rubber products, reduce compression set, and improve filler dispersion and interaction within the rubber compound.

Commonly used in light-colored rubber products, such as those in the footwear industry.

Suitable for various rubber systems, including natural rubber, isoprene rubber, styrene-butadiene rubber (SBR), butadiene rubber (BR), and nitrile rubber (NBR).
