Covestro introduces sustainable textile coating option, Impranil CQ DLU

Covestro has unveiled a new aliphatic polyester carbonate polyether polyurethane (PU) dispersion named Impranil® CQ DLU. This textile coating solution contains approximately 34 percent plant-derived carbon, expanding the range of partially bio-based dispersions for textile coating. The product is a sustainable alternative to the widely used purely petroleum-based Impranil DLU.

Impranil CQ DLU offers the same outstanding properties as its petroleum-based counterpart, Impranil DLU. With a high solids content of 55 percent, customers can seamlessly replace Impranil DLU with Impranil CQ DLU in their processing operations, achieving an additional increase in textile coating sustainability. This transition aligns with the growing importance of sustainability in purchasing decisions for both industries and consumers.

Impranil CQ DLU is suitable for creating synthetic materials for various applications, including sports articles, technical textiles, car interiors, and bags. Coatings based on this dispersion exhibit excellent hydrolysis resistance, lightfastness, high tensile strength, scratch resistance, and a pleasant feel. The dispersion can be used for both intermediate and top coats, and application methods range from direct or transfer coating to printing processes and microfiber dipping.
