SEPAWA Congress 2006: WACKER SILICONES Presents Novel Silicone Emulsion for Impregnants

Munich, Sep 05, 2006

At the 53rd SEPAWA Congress (from October 11-13 in Würzburg, Germany) WACKER SILICONES will be presenting a novel silicone emulsion which for the first time enables the manufacture of highly effective water-based silicone impregnants for various household care applications. The product does not use emulsifiers, thereby blazing the trail to a new generation of water-based impregnants. These impart a markedly hydrophobic (e.g. water-repellent) surface to textiles, wood and leather. A particularly interesting household application for emulsifier-free silicone impregnants is the refreshing of textile impregnations in the washing machine’s rinse cycle.
Previously, water-based systems and good hydrophobation were considered incompatible. The reason for the relatively poor hydrophobic effect of this system is the reliance on emulsifiers as stabilizers. They remain in the impregnant film, significantly impairing its hydrophobic effect. This contradiction has been solved via WACKER’s novel emulsifier-free product WACKER® HC 303 VP. It provides an uncompromised silicone film that completely repels water and other aqueous liquids such as red wine and coffee.
WACKER® HC 303 VP is a clear, colorless and odorless, low-viscosity oil-in-water microemulsion which can be easily processed into finished impregnants. Following application to the impregnating surface, a silicone film forms – already at room temperature – and bonds to the substrate.
WACKER® HC 303 VP is particularly suitable for the production of impregnations applied to textiles in the washing machine. Impregnations based on this novel product can be added during the washing machine’s rinse cycle (directly after the wash cycle) instead of a softener. This way, textiles can be imparted with water-repellent impregnation – without requiring additional consumer time and effort. For other porous surfaces, the impregnant is applied as a pump spray or via brush, rag or sponge. To impregnate suede and wood, the modified product WACKER® HC 304 VP is available.
