Impranil® 43031 Lösung is a one-component polyester urethane based on an aliphatic diisocyanate. It has a viscosity at 23°C of 7,000-15,000 mPa·s, and a non-volatile content (0.9–1.1g/1h/125°C, convection oven) of 25 ± 1°C. Impranil® 43031 solution is used as a topcoat and finish for PVC coatings requiring high surface smoothness and reduced migration of PVC plasticizers.
It is also suitable for use as a topcoat for lining materials, especially for shoe linings with an adhesive polyurethane coating and for polyurethane, PVC and polyacrylate foams used on suitable non-wovens, wovens, knitted fabrics and coagulated substrates. Impranil® 43031 solution is also used as the harder component in blends with other aliphatic Impranil® and Desmoderm® Finish products.
