Import 3,3,3-Trifluoropropyl) Methyldimethoxysilane — Buy in Bulk from Supplier in China

LS-M531 is a silane coupling agent designated 3,3,3-trifluoropropyl)methyldimethoxysilane with CAS number 358-67-8 and EINECS registration 206-619-1. The compound is supplied as a colorless transparent liquid with a minimum purity of 98.0% determined by gas chromatography. Its molecular architecture combines a trifluoropropyl group with a methyldimethoxysilane moiety, conferring both fluorocarbon hydrophobicity and silane reactivity in a single molecule.

The two methoxy substituents on silicon undergo standard hydrolytic condensation, allowing this silane to form siloxane bonds with inorganic substrates and condense with suitable organic resins. The trifluoropropyl segment introduces low surface energy and chemical resistance characteristic of fluorinated materials. Typical silane coupling agents of this class hydrolyze in moist environments to generate reactive silanol groups that couple with metal oxides, glass, and other hydroxyl-bearing surfaces.

Primary applications span fluororesin adhesion promotion, waterproofing and oil-repellent treatments for cultural artifacts, masonry, metals and wood, plus hydrophobic finishing of natural fibers including wool, cotton and leather to reduce water retention. Glass surface modification for anti-fouling properties represents another established use. Buyers should confirm with Nanjing Silfluo New Material Co., Ltd. the specific packaging format, minimum order quantity and available Incoterms for this reactive specialty chemical.
