Desmodur® N for cutting-edge refinish coatings

Copied to clipboard

Our innovative design concept for electric vehicles reflects current trends in surface design. Through the use of synthetic materials these developments offer new perspectives for comfortable, functional and energy-efficient cars with a clear focus on lightweight constructions.

Task

A high-performing coating for e-mobility

To underline the technological features of our design concept, we were looking for an experienced and competent partner to collaborate with us on new high-performing coatings for electric vehicles.
Challenge

Produce a top-quality coating that is also sustainable

A high-quality coating was required that fulfills high sustainability, efficiency and performance demands in line with this innovative mobility design concept.
Solution

A low-viscosity isocyanate crosslinker with high performance standards

The innovative automotive refinishing paint system developed by R-M® (a premium BASF coating brand) based on the waterborne basecoat and the clearcoat of our Desmodur® N 3900 low-viscosity isocyanate crosslinker almost matches the high performance standards of modern polyurethane OEM coatings.The pigment basecoat Verbosian Orange was exclusively designed to highlight the innovative power and technical appearance of electric vehicles. “Orange as a color has the properties of attentiveness and presence while also being very warm and emotional. In other words, orange ideally represents energy,” explains Mark Gutjahr, Head of Automotive Color Design Europe at BASF. The clearcoat that protects the colored coating layer below is based on our polyurethane raw materials and cures rapidly, even at low temperatures. Other advantages include very good coating adhesion and excellent flow thanks to its low viscosity.
