Durr develops paint application with high edge definition and no overspray

0 Comments

Germany’s Durr has developed a new technique that applies paints over large areas or in simple patterns with high edge definition – and absolutely no overspray. The innovative EcoPaintJet applicator won this year’s innovation award ‘Deutscher Innovationspreis’ in Germany, and is now available for the general industry in an easily integrated set. Paint company Adler has developed paints tailored to the new application technology.

In woodworking, shipbuilding, electronics manufacturing, and many other industry sectors, product and component surfaces are coated to protect them or add colour. This previously involved a great deal of effort if the coating had to be applied with high edge definition since the surfaces either need to be manually masked or film-wrapped. There is also a significant amount of waste, both in terms of adhesive tape and paint loss due to overspray. According to Durr, with the new overspray-free application set, both of these challenges are a thing of the past. EcoPaintJet, the innovative applicator contained in the set, is already successfully in use in automotive series production. Since 2019, the new Dürr technology has made it possible to paint car roofs in contrasting colours with no masking.

More options for painting
The EcoPaintJet applicator delivers precise coating with no overspray. This increases coating efficiency and offers companies more options when it comes to product design and the transportation of goods. Instead of adhesive film, decorative surfaces can be protected for transport through the targeted application of a spray film. This can be simply pulled off again at the destination.

The technology also enables new options for the function and design of products. For example, the precise coating method means that window frames can have a weatherproof coating applied to the outside and get a decorative or differently colored application on the inside. Decorative effects
