  • ADDSiL™ 8311 silicone wetting agent is a thermostable silicone additive which, in contrast to conventional silicones, shows no thermal decomposition at high temperature.

  • ADDSiL™ 8311 is silicone based surface additive for solvent-borne and UV curing system. It can provide strong reduction of the surface tension of coating systems. It therefore particularly improves substrate wetting and avoids cratering. Surface slip and gloss are also increased.

Packing and Storage

  • ADDSiL™ 8311 for clear silicone paint is supplied in 20Kg / 180Kg plastic drum or steel drum or according to customer’s request.

  • In the original unopened packaging, ADDSiL™ 8311 has a shelf life of 24 months.
