DirectCoating Technology for highly attractive design possibilities for car interiors

The coating manufacturer Votteler was looking for a process to create surface designs in multiple colors and textures for new and attractive car interiors.

Creating a variety of high-quality decorative car components in the most productive way was what Votteler was particularly looking for, as the automotive industry needs to manufacture components efficiently.

Our DirectCoating Technology, based on Desmodur® and Desmophen®, allows seemingly contradictory wishes to be fulfilled by coating components in a two-stage process. Initially, the plastic substrate is injected into the first cavity of the mold; then the component is transferred to a second cavity that is slightly larger – by the exact thickness of the coating layer. The solvent-free coating is then injected into this cavity through a reaction injection molding (RIM) mixing head. The result is a polyurethane-coated component that displays outstanding car interior properties but needs very little re-working. “With DirectCoating Technology we can offer completely new interior designs to the automotive industry. The continued development of PURIFLOW Coating Systems enables us to realize a nearly unlimited degree of exciting surface properties, such as exceptional scratch resistance and self-healing effect. Additionally, we can offer PURIFLOW Systems from colorless to tinted up to new metallic accents and from soft leather haptic up to hard metal accents. These are only some of the unique features with which decorative plastic parts can be fast and efficiently finished through DirectCoating Technology – and without any external release agent,” says Manuel Seiz, Business Unit Manager at Votteler
