Applications:
Vinyltris(methylethylketoxime)silane is used as a neutral curing agent in silicone sealant formulations.
In most cases Vinyltris(methylethylketoxime)silane is used in combination with methyloxime silane.
Compared to formulations based on methyloxime silanes only, the use of combinations containing methyl- and vinyloxime silanes leads to a shorter skin formation time of the silicone sealant without a reduction of the curing time.
The ability of the sealant to withstand stress early, required for a certain elasticity and tear resistance, is achieved.
Packing:
Packed with 5L, 20L or 210L plastic/steel drum, 1000L IBC container, or according to customer

Applications:
Polymer Modification: Vinyltrimethoxysilane is used to modify polyethylene and other polymers by grafting its vinyl group to the polymer backbone using a radical initiator, such as peroxide. This provides a polymer with pendant trimethoxysilyl groups that may be used as moisture-activated crosslinking sites via hydrolysis of the alkoxy groups followed by condensation of the resulting silanols.
Crosslinking of Silane-Grafted Polymers:
The reaction of Silane-grafted polyethylene to form a crosslinked or vulcanized polyethylene uses water to form the crosslinks. This technology is widely used around the world for commercial applications in wire and cable insulation, tubing, and other similar uses.
The basic reaction sequence is as follows: polyethylene is reacted (grafted) with vinyltrimethoxysilane, using a peroxide initiator, in an extruder. The grafted polyethylene is then formed into a finished product, such as cable jacketing, wire insulation, or pipe. The forming step is usually done by a second extrusion, during which a catalyst for the moisture-cure step is added. Finally, the formed article is exposed to moisture or hot water to cause hydrolysis of the Silane and condensation to form crosslinks via Si-O-Si bond formation.
Packing:
Packed with 5L, 20L or 210L plastic/steel drum, 1000L IBC container, or according to customer’s requirement.
