Application: SILFOAM® SC 129 is based on high-molecular polysiloxanes and has an average viscosity of approx. 12,500 mPa*s. Even small amounts are particularly effective in suppressing foam in laundry detergents and systems with a high surfactant concentration. By virtue of its structure, SILFOAM® SC 129 can be used in smaller amounts than conventional silicone antifoam agents. This makes it particularly suitable for use in detergents and other formulations with a high surfactant concentration to ensure considerably more persistent foam suppression. Despite its comparatively high viscosity, it is readily dispersible in aqueous surfactant formulations. Apart from laundry detergents, SILFOAM® SC 129 is useful in wetting-agent-containing systems whose efficiency is reduced by the action of shearing and dispersion forces. SILFOAM® SC 129 also has a foam-suppressing and deaerating effect on anhydrous synthetic resins.
