Evonik VQM 973

Evonik VQM 973 formulations consist of vinylfunctional QM resin and vinylfunctional silicone polymers. These formulas are used to produce materials that are transparent, free of fillers, and have great mechanical qualities. They can also improve the mechanical properties and flow behavior of systems that are filled.

Applications

In transparent silicone formulations Polymer VS can be either partially or fully replaced with VQM products. In filler-containing formulations VQM can be used as a substitute for both, Polymer VS and some of the filler and/or silica. Please note that the vinyl content of VQM products is higher than that of Polymer VS grades of comparable viscosity. This can generally be offset by increasing the SiH content (Crosslinker 100/200 series).
