A successful trial took place at Benseler Beteo in February. In cooperation and support with Dörken, represented by Sabrina Hilbt and Emre Kocak, screws of various dimensions were coated on a large coating system under series production conditions with a full load. The screws were provided by the customers Richard Bergner and Lisi Automotive and pre-treated by Benseler.
Coatingusing the dip spin process
The coatingwas applied using the dip spin process with the zinc flake basecoat Delta-Protekt KL100 and the new, series-ready topcoat Delta-Protekt TC 502 GZ. Both products are PFAS-free. The coating test went smoothly and the parts were then additionally coated with threadlockers to test their compatibility with the anti-corrosion coating.
Successful tests in the Benseler laboratory
The tests subsequently carried out in the Benseler laboratory confirmed the good results: The parts consistently exhibited very good corrosion protection results, with over 720 hours in the salt spray test, as well as very good friction coefficients and bolting properties. The coating is therefore suitable for series production. Further tests with coatingsfor black surfaces are planned.
