Water-based textile-impregnating agents are better for the environment, but have mostly failed to match the efficacy of solvent-based products. The reason for the relatively poor hydrophobic effect of this system is the reliance on emulsifiers. While emulsifiers are necessary for stabilizing aqueous emulsions, their surface activity yields an undesirable side-effect: during film formation, the emulsifier molecules accumulate at the interfaces between the coalescing polymer or wax particles, forming hydrophilic microchannels which allow water to diffuse right through to the substrate's surface.
This problem was solved with TayChem SFE 303E. The silicone emulsion is a clear, low-viscosity oil-in-water microemulsion. Following application to the impregnating surface, a silicone film forms at room temperature and bonds to the substrate. Thus, the product provides an uncompromised silicone film that completely repels water and other aqueous liquids.
The silicone emulsion is colorless and odorless and can be easily processed into finished impregnants. The results of the technical tests indicate that TayChem SFE 303 E is ideal for restoring the factory impregnation of textiles. It imparts a highly hydrophobic surface finish that completely repels water and aqueous liquids such as red wine, coffee and fruit juice.
TayChem SFE 303 E can serve as a basis for developing highly effective, water-based impregnating agents for consumers and industrial and institutional users. Impregnations based on the product can be added during the washing machine’s rinse cycle instead of a softener in order refresh the existing impregnation. Typical applications are the reimpregnation of outdoor clothing, neckties, tablecloths, work clothes, laboratory coats and uniforms.
