Dabco® SI3101

Dabco® SI3101 by Evonik is a silicone surfactant. Possesses excellent foam surface quality with reduced voids. It is a non-hydrolysable structure for excellent premix stability, good compatibility with rigid foam polyol pre-blends. Provides very efficient emulsification, nucleation and stabilization, resulting in fine, uniform foams with excellent insulation properties. Exhibits low viscosity and low freezing point allowing for easy handling and accurate pumping. Used in all polyether rigid PUR formulations, appliance formulations, continuous and discontinuous insulation panels (flexible and metal faced). Dabco® SI3101 recommended use level ranges from 1.0 to 2.5 pph polyol.
