Description of Phenyltrimethoxysilane

CFS-921, Phenyltrimethoxysilane is a functional silane with a phenyl group and a reactive methoxy group. The phenyl functionality enables CFS-921 to perform excellently even under high temperature conditions. With the presence of a trimethoxy group, CFS-921 can hydrolyze rapidly and form chemical bonds to various inorganic substrates. It is normally used to replace Momentive Silquest A-153, Dynasylan 9165, ShinEtsu KBM-103 or Dow Corning Z-6124, as their counterparts or equivalents.

Application of Phenyltrimethoxysilane

CFS-921 can be used as a surface modifier and a dispersion agent of a variety of inorganic materials. It can improve wettability and dispersibility of mineral-filled polymers.
CFS-921 can be used as a crosslinker for organic resins and especially used in coatings, sealants and adhesives.
CFS-921 can be used as a hydrophobic additive to other silane coupling agents.
CFS-921 can be used as a raw material to produce phenyl silicone fluids and silicone rubbers.
CFS-921 can be used as an electron donor in the process of polypropylene polymerization.

Packaging of Phenyltrimethoxysilane

CFS-921 is offered in 25L PE pails, 200L PVF steel drums and 1000L IBC totes.
Please contact Co-Formula customer service team for any special packaging request.

Storage of Phenyltrimethoxysilane

CFS-921 should be stored in a cool, well-ventilated place, and avoid exposure to humidity.
CFS-921 should be stored in its original containers and used up as soon as possible after opening.
When stored in a strictly sealed and unopened container, CFS-921 has a shelf life of 12 months.
