Together with designer Miika Heikkinen, Covestro's Coatings & Adhesives and Engineering Plastics segments have developed a door panel concept with new material solutions. The prototype contains a waterborne coating with innovative INSQIN® technology in combination with an adhesive based on a Dispercoll® U 66 dispersion–two waterborne polyurethane (PU) solutions with low levels of VOCs. Specially developed to provide cost-effective and sustainable applications for future automotive interior requirements, they provide translucent appearance, coating adhesion, and deep color effects in door panels.
As a vegan solution, the lower CO2 emissions and reduced energy consumption of INSQIN can reduce the overall CO2 footprint of plastics by up to 45% while providing virtually odor-free indoor air quality. The carbon footprint can be further improved by using an Impranil® CQ DLU PU dispersion, which consists of approximately 35% renewable carbon by weight. In addition, the application also includes a partially bio-based, water-based, soft-touch coating with up to 33% renewable carbon in the final formulation.
An anionic high-molecular-weight polyurethane dispersion, Dispercoll U 66 is suitable for the formulation of thermally activated adhesives. The water-based dispersion is well suited for adhesive applications with low thermal activation temperatures and with improved climate resistance.
