The Dow Chemical Co. Midland, MI/USA, has introduced Dowsil IE-8749 Emulsion, a new generation of durable water repellent finishes for fabrics based on silicone chemistry.
Studies conducted on a variety of textiles substrates based on Dowsil IE-8749 Emulsion treatment demonstrate improved fabric retention compared to standard silicone finishes – thereby providing continued water repellency after multiple washes. Unlike many conventional finishes, Dowsil IE-8749 Emulsion finish does not need to be regularly heat treated to restore the water repellency performance, which is a key advantage for the durability of the final product. By incorporating it into their finishing processes, textile finishers receive greater control over the hand of the fabric. Depending on specific need, this can range, from a very soft hand that is characteristic of silicone when used alone, to a firmer hand with the addition of cross linkers.
The technology powering Dowsil IE-8749 Emulsion was developed through a collaboration between Dow and Nicca Chemical Co. Ltd., Fukui/Japan. It does not contain fluoroalkyl or fluorocarbon.
