MRC -- Covestro launches a new aliphatic polyester carbonate polyether polyurethane (PU) dispersion for textile coating under the name Impranil CQ DLU, in which around 34% of the carbon contained is of plant origin, said the company.
Impranil CQ DLU expands the existing range of partially bio-based dispersions for textile coating with a product whose purely petroleum-based variant Impranil DLU is very popular with customers. To gradually move away from petroleum and other fossil raw materials, Covestro is increasingly relying on alternative raw materials from renewable sources, including those from biomass.
Since the new dispersion has the same outstanding properties as the established one, as well as a high solids content of 55%, customers can now replace Impranil DLU one-to-one with Impranil CQ DLU in their processing operations and thereby easily achieve an additional increase in textile coating sustainability. Sustainability is increasingly becoming a key purchasing criterion not only for the industry, but also for brand owners and consumers. CQ stands for 'Circular Intelligence'.
The core idea of the CQ concept is to label Covestro products if the alternative raw material base exceeds a content of 25%. As the raw material for INSQIN technology, the established Impranil DLU already enables aqueous textile coating without the use of solvents. The ecological footprint of such a coating is significantly lower than that of solvent-based systems. Impranil CQ DLU is suitable, among other things, for producing synthetic materials for sports articles, technical textiles, car interiors and bags.
Properties of coatings based on the new high-performance dispersion include excellent hydrolysis resistance, very good lightfastness as well as high tensile strength and scratch resistance. In addition, the coatings have a pleasant feel and good alkali resistance. Impranil CQ DLU can be used for both the intermediate coat and the topcoat. The dispersion can be applied in various ways. The spectrum ranges from direct or transfer coating to printing processes and microfibre dipping.
We remind, Covestro has forged a global partnership with Chinese automotive trim company Xinquan Automotive at the China International Import Expo in Shanghai. This alliance seeks to strengthen the China business and enhance international collaboration, supporting Xinquan’s expansion into North America, Europe, and ASEAN countries.
