Advancements in Sustainable Textile Coating Technology

Climate protection necessitates a steady shift away from petroleum and fossil raw materials towards renewable raw materials. As a result, Covestro is becoming more dependent on alternative raw materials, such as those derived from biomass.

Under the brand name Impranil CQ DLU, the company has started to offer an innovative aliphatic polyester carbonate polyether polyurethane (PU) dispersion for textile coating, with around 34% of the carbon derived from plants. Impranil CQ DLU expands the existing spectrum of partially bio-based dispersions for textile coating by introducing a product whose solely petroleum-based equivalent, Impranil DLU, is well-received by customers.

Impranil CQ DLU is potentially used to make synthetic materials for sportswear, technical textiles, automobile interiors, and bags, among other uses. Impranil CQ DLU can be used as an intermediate coat as well as a top coat.

People can now directly replace Impranil DLU with Impranil CQ DLU in their processing steps. This will easily improve the durability of textile coatings even more, since the new dispersion has the same great qualities as the old one and a high solid content of 55%.

The CQ concept's central view is to designate Covestro products if the alternative raw material base reaches a content of 25%, as in this case.
