High Solids

June 1, 2010

Bayer MaterialScience LLC, a leader in polyurethane chemistry, recently announced the availability in the North American market of new high-solids, fine-particle polyurethane dispersions for the formulation of textile coatings.

These high-solids products, which offer environmental and economic advantages for applicators, were developed for various textile applications and markets, which include automotive interior and contract upholstery.

The new products are Impranil LP RSC 1554 polyurethane dispersion gives textiles more volume and body; is well suited to sporting goods and interior furnishings; Impranil LP RSC 1380 polyurethane dispersion improves the haptic properties of synthetic leathers in sporting goods and interior furnishings; Impranil LP RSC 1537 polyurethane dispersion characterized by its softness and flexibility, this specialty product is well suited to the creation of an adhesion layer that is subsequently transferred to the textile together with the top layer.

From an economic and logistical perspective, these new aqueous dispersions help make the textile coating process more efficient, said Scott Grace, technical director, Waterborne Business Development, Coatings, Adhesives and Specialties, Bayer MaterialScience LLC.Because these dispersions feature solids content of up to 60 percent, the inventory amount of raw materials that is needed can be reduced. Furthermore, applicators can achieve higher film builds in one coat, reducing the number of overall coats that are necessary. Also, processing is more efficient because less water needs to be evaporated, and fewer stabilizing additives are required.
