Bayer introduces new raw materials for the coating of textiles
Bayer, manufacturer of the Impranil line of polyurethane dispersions - raw materials for the coating of textiles for outerwear, bags, luggage and fashion shoe uppers – is presenting new waterborne polyurethane dispersions with 60% elevated solids content at the Asia Pacific Leather Fair 2005 in Hong Kong.
One of the dispersions, Impranil LP RSC 1537, was designed for new technical applications but has properties similar to those of Impranil DLP Dispersion. The products are suitable for mechanical foaming and are characterised by high abrasion resistance, lightfastness and flexibility.
"We developed Impranil LP RSC 1537 primarily for upholstery, automobile seats, sporting goods and other technical articles," says Rolf Irnich, a specialist for textile coating and coagulation at the Business Unit Coatings, Adhesives, Sealants of Bayer MaterialScience. "One advantage of the high solids content is that high film thicknesses can be achieved with a single pass. Also noteworthy is that the coating is
very environmentally friendly because only waterborne dispersions are used."
Another example is Impranil DLN Dispersion, used for the formulation of fashion coatings and the finishing of non-wovens. The company has also developed a new grade of this product having a solids content of 60%, which it markets under the name Impranil LP RSC 1380.
Bayer says polyurethane leather is becoming increasingly popular as an alternative to natural leather due partly to its economical production, durability and leather-like properties. Impranil, Impraperm and Desmoderm product lines for applications in the automotive, furniture and shoe industries are currently at the forefront of Bayer’s developments formulated with raw materials.
