MORE SOLIDS, LESS SOLVENT
24 March 2005 - Bayer MaterialScience AG

The Impranil® line of polyurethane dispersions from Bayer MaterialScience AG are well-established and proven raw materials for the coating of textiles for outerwear, bags and luggage and fashion shoe uppers.

Available with solids contents of 40 or 50 percent, the products are suitable for mechanical foaming and are characterized by high abrasion resistance, lightfastness and flexibility. At the Asia Pacific Leather Fair 2005 in Hong Kong, Bayer MaterialScience is presenting new waterborne polyurethane dispersions characterized by an elevated solids content of 60 percent. Impranil® LP RSC 1537, for example, was designed for new technical applications but otherwise has properties similar to those of Impranil® DLP Dispersion.

“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, which is used for the formulation of fashion coatings and the finishing of non-wovens. Bayer MaterialScience has also developed a new grade of this product having a solids content of 60 percent, which it markets under the name Impranil® LP RSC 1380.

Polyurethane leather is becoming increasingly popular as an alternative to natural leather. This is due in part to its economical production, but above all to its properties, which are at least equal – and in some aspects superior – to those of natural leather. Although the two materials are to a certain extent indistinguishable in terms of appearance, polyurethane leather based on Impranil® or Desmoderm® products from Bayer MaterialScience stands out in particular through its better durability. Furthermore, individual properties can be specifically modified to suit the respective application, e.g. more comfortable seating in automotive interiors or good abrasion resistance, which is essential in the case of soccer balls.
