SiSiB® PC6120 Vinyltriethoxysilane

SiSiB® PC6120, vinyltriethoxysilane, is a vinyl-functional silane that may be used to improve the bond between glass fiber or mineral fillers and resins that are reactive towards the vinyl group. It is also employed to functionalize resins via free radical mechanisms - copolymerization or grafting - and to modify surfaces.

SiSiB® PC6120 vinyl silane is the equivalent of Momentive's A-151, Dow's Z-6518, Wacker's GF56, Evonik's Dynasylan VTEO silane, ShinEtsu's KBE-1003 silane.

Reactivity: In the presence of moisture the ethoxy groups of SiSiB® PC6120 hydrolyze to produce ethanol and reactive silanol (Si-OH) groups which can bond to a variety of inorganic substrates or react with each other to form siloxane bonds (Si-O-Si). The organophilic vinyl end of SiSiB® PC6120 can also react with a suitable polymer (activated by peroxide or radiation).

Application

SiSiB® PC6120 is suitable for the preparation of moisture-curing polymers, e.g. polyethylene. Silane chinacrosslinked polyethylene is widely used as cable isolation, and sheathing mainly in low voltage applications as well as for hot water/sanitary silicone pipes and underfloor heating.

SiSiB® PC6120 is used as a co-monomer for the preparation of different polymers such as polyethylene or acrylics. Those polymers show an improved adhesion to inorganic surfaces and they can also be crosslinked with moisture.

SiSiB® PC6120 is used as an efficient adhesion promoter for various mineral-filled polymers, improving mechanical and electrical properties especially after exposure to moisture.

SiSiB® PC6120 is used to improve the compatibility of fillers with silicone polymers, leading to a better dispersibility, reduced melt viscosity and easier processing of filled plastics.

SiSiB® PC6120 is used to pretreat of glass, metals, or ceramic surfaces, improve the adhesion of coatings on these surfaces and corrosion resistance.

SiSiB® PC6120 is used as moisture scavenger. SiSiB® PC6120 reacts rapidly with water. This effect is used widely in sealants.
