Modifier 710 is a SiH-terminated polydimethylsiloxane for the use as a reactive plasticizer in addition-curing silicones. Due to the difunctional structure, this product does not react by crosslinking, but by extending the chains of vinyl-terminated silicone polymers (Polymer VS). Using Modifier 710 reduces the crosslinking density and therefore the elastomer hardness. It allows creating low viscous formulations with highest elongations.
Typical Applications
Use of the modifiers allows obtaining products with a low Shore hardness, even when using low-viscosity vinyl polymers. These modifiers are therefore used in formulations that have a low viscosity prior to crosslinking and should have low Shore hardness after crosslinking. Another important modifier application is the formulation of silicone gels.
When working with two-component silicone formulations, it must be ensured that Pt-catalyst (e. g. Catalyst 500 series) and modifier are kept strictly apart.
