Silane series DLC-V71E

Chemical Name 






Molecular Structure


Molecular Formula




DLC stands for Dry Liquid Concentrate, and CapatueTM DLC-V71E dry silane is a convenient form of traditional liquid organo-functional silane coupling agent Vinyltriethoxysilane with 65% high active concentration; it is a free-flowing powder. DLC-V71E dry silane offers the benefit of easier handling and weighing, quicker incorporation during mixing and a longer shelf life.

This product has a vinyl organo-functional group and can be over a broad range of applications to provide superior bonds between inorganic substrates and organic polymers. The vinyl function reacts with a wide array of thermoset, thermoplastic and elastomeric materials.

DLC-V71E dry silane functions by chemically coupling the filler to the backbone of the polymer during vulcanization, compounding or crosslinking, and it can be used at peroxide and metal oxide curing systems.
