Siwin is a leading manufacturer and supplier of organosilanes for over 15 years.

Besides common used silanes such as amino, epoxy and vinyl silanes, Siwin also supply silanes with specific functions for specific abilities. Siwin phenyl silanes are used to synthesize phenyl silicone oil, phenyl silicone resin and phenyl silicone rubber. Siwin phenyl silanes are also be used for resin modification to provide high and low temperature resistance.

Siwin-P31 (Phenyltrimethoxysilane) and Siwin-P32 (Phenyltriethoxysilane) can improve thermal stability of other silanes. Can be used as other silanes and siloxanes intermediates.  

A.Mineral Fillers: as a surface modifier for the aluminum trihydrate (ATH) used as a filler in halogen-free flame-retardant (HFFR)cable insulation

B.Silicones: as a crosslinker in high-temperature silicone elastomers

C.Catalysts: as an electron donor ("A-donor") in the polymerization of polypropylene.

Siwin- PTOH (Triphenylsilanol, CAS No. 791-31-1) can increase the thermal and flame-retardant properties of resins, used as a terminator for linear polysiloxanes, molecular weight regulator for polymerization reactions, protective agent for organic reactions.

Main raw material for the synthesis of bis(triphenylsilyl)chromate esters

3D printing consumables

Siwin-P2OH (Diphenylsilanediol CAS NO.947-42-2) can be used in following applications:

Can be used for preparing high - performance coatings and films, improving the weather resistance, corrosion resistance and insulation of materials.

As raw materials for high - performance silicone adhesives and sealants.

Used as initiators and cross - linking agents in polymer synthesis to improve the properties of polymers.

As raw materials for glass fiber sizing agents to improve the strength and insulation of glass fibers.

Applied in fields such as paper processing, leather treatment, and pesticide synthesis.
