Digital printing for automotive coatings: Covestro expertise contributes to pave the way

Digital printing: transformation for automotive coatings

Today, car producers typically apply multi-layered coatings using spray application. Automotive standard 1K/2K polyurethane coatings based on Desmodur® polyisocyanates from Covestro, offer proven chemical-, scratch- and weather resistance along with high gloss and a clear, transparent surface finish. Yet, at the same time, spray application results in overspray and can add the process complexity of masking if car body parts in two or more colors are needed. Furthermore, spraying the varnish effectively prevents the continuous production of individualized car bodies. 

For automotive OEMs and coating suppliers, 2D printing technology presents a major opportunity to combine the precise digital application of coatings with the flexibility of customized production. For companies considering this transformation, Covestro offers digital processing know-how along with a range of Desmodur® based automotive coating material solutions which are already optimized for 2D digital printing applicators. 

Process expertise and material solutions for 2D printed coatings

Desmodur® polyisocyanates from Covestro offer tremendous formulating freedom for polyurethane (PU) coatings that provide exterior surface protection for cars, trucks, and busses. With non-yellowing, aliphatic formulations that are specifically tailored to the digital printing process, Desmodur® based coatings offer the chemical resistance, scratch resistance, and high gloss expected by automotive manufacturers. At the same time, the 2D printed coatings are weathering stable, highly transparent, and resist UV radiation.  

Thanks to our expertise in both digital processing and in material solutions to match it, Covestro is a trusted partner for assisting automotive partners in taking advantage of these new coating technologies. 

Working with us, automotive OEMs and their partners can calibrate a precise digital application of coatings having no overspray or masking, without having to sacrifice reliable Desmodur® protection. Covestro can assist you on the journey with process expertise and material solutions, that will meet your digital coating application needs.
