Highly Wear-Resistant VESTAKEEP® PEEK Coatings: Evonik and IBEDA Cooperate in Flame-Spray Process
VESTAKEEP® coatings applied with this process yield extremely wear-resistant surfaces with outstanding chemical resistance. VESTAKEEP® is hydrolytically stable, with a long-term thermal stability of 260°C (500°F). These properties make it an ideal material for use in such industries as medical technology, aeronautics, automotive, oil, and power. Wolfgang Christoph, an Evonik expert with 25 years of experience in the area of powder coating: "With our know-how and expertise in flame-spraying, we've found an ideal partner in IBEDA for offering our customers a complete solution that meets the highest standards."
Flame spraying, developed early in the last century, is one of many types of thermal spraying processes. In this process, the combustion of a gas/oxygen mixture generates the thermal energy to melt the powder and warm the surface of the substrate. A carrier gas-normally compressed air-serves as the medium for transporting the melted particles to the substrate surface. The advantages of this process include low investment costs and the option of coating large parts on site, without an oven. VESTAKEEP® 2000 FP is best suited for this application because it has a sufficiently low melt viscosity.
Evonik has been successfully producing and marketing high-performance polymers for over 40 years and is highly regarded in the market for its technical service experience. On this platform, the company has transferred its know-how in powder technology, among other things, to VESTAKEEP® powder, which it recently added to its portfolio in 2008, and offered it to its newly acquired development partners. The cooperation is for the long run and involves extended accreditation periods.
IBEDA Sicherheitsgeräte und Gastechnik GmbH & Co. KG is one of the world's leading producers of safety equipment and meets all of the most important international and European standards, as well as those at the national level. IBEDA develops and manufactures high-quality fixtures for gas safety engineering, products for central gas supply and autogenous engineering, as well as equipment and complete units for thermal spraying.
