Impranil® DLN-SD is a new a water-based polyurethane (PU) dispersion suitable for formulating biodegradable textile coatings.

“Raw materials from Covestro enable the production of biodegradable coatings, but also composite solutions,” said Torsten Pohl, Ph.D., global head of textile Coatings. “As a result, they contribute to a modern circular economy.” Tests reportedly show that more than half of the PU dispersion is degraded within 28 days under the special conditions of the OECD 301 standard. Therefore, the degradation rate is higher than that of polyacrylates and other film formers.

Since it is an aliphatic PU dispersion, it can be used to formulate highly light-resistant coatings. The dispersion can reportedly be used in adhesive, intermediate and surface coatings. Biodegradable coatings based on the dispersion have the potential to follow the trend toward more sustainable products.
