CFS-838, 3-Glycidoxypropyltrimethoxysilane is a primary epoxy functional silane with a rapid hydrolysable trimethoxy group. It can improve adhesion to inorganic materials such as fillers, dyes, metals, glass fibers. Better wettability and superior adhesion will be achieved with the presence of CFS-838. It is the equivalent of Momentive Silquest A-187 or Dynasylan GLYMO. It can be also described as 3-(2,3-Epoxypropoxy)propyltrimethoxysilane.
