Product Application Of Propyltrimethoxysilane Cas 1067-25-0

  1. Powder Modification: Propyltrimethoxysilane is  used for hydrophobic modification of inorganic fillers such as silica, talc, and quartz powder to improve powder dispersibility and compatibility.
  2. Coupling Agent: Trimethoxypropylsilane is used for coupling between glass fiber, inorganic minerals, and polymer materials to enhance the mechanical strength of composite materials.
  3. Coatings and Adhesives: Propyltrimethoxysilane is added to waterproof coatings, sealants, and resin systems to improve water resistance, weather resistance, and adhesion to substrates.
  4. Surface Treatment: Trimethoxypropylsilane is used for hydrophobic and stain-resistant treatment of glass, stone, and metal surfaces; also serves as an intermediate in silicone synthesis.
