Methacrylate monomers for Textile Applications


Water and oil-repellent agents come in the form of an acrylic emulsion polymer that can be used for special applications in the textile industry. It provides durable liquid repellency without compromising the natural feel of cotton, for instance. Textile treatments using this type of chemical result in a host of consumer benefits, such as preventing soiling for a longer period, faster drying and protection from rain. These articles can be used for the most diverse applications, including outerwear, upholstery, rugs, carpets, protective clothing, uniforms, table cloths, wallpaper etc.

The newest generation of water and oil-repellent agents is based on fluorochemicals. These products are typically manufactured by emulsion polymerization using 30-60% perfluoroalkyl ethyl methacrylates and 30-50% long side-chain methacrylates. Long side-chain methacrylates, such as VISIOMER® C13-MA and VISIOMER® C17.4-MA, improve water resistance while reducing the dosage of the more expensive perfluoroalkyl ethyl methacrylates.

The emulsion is then usually diluted to a solid substance concentration of <1.0%. The textile is dipped in the emulsion, squeezed and then dried/cured at a temperature of up to 170°C for 1-2 minutes.
