Xylar 1 / Xylan 1070
Xylar 1 is a ceramic-metal coating, which offers resistance to oxidation at high temperatures and long-term salt fog protection. Xylar 1 can be applied without post-treatment and is usually used as a base coat for materials, after which a top coat is applied.
This top coat is usually Xylan 1070 by Whitford. This is a PTFE coating, also called fluoropolymer coating, based on an organic solvent and it was initially developed at the beginning of the 1970s for coating fastening materials. This combination of Xylar 1 with Xylan 1070 provides excellent corrosion protection, neutral salt spray test up to 4000 hours. The friction coefficient is also very low, lower than, for example, electrolytic zinc plating. The combined layer thickness of these 2 coatings is usually approximately 50 mu and the processed materials can be used at temperatures ranging from -195° C to +535°C for Xylar and from -195° C to +260° C for Xylan 1070.
The process required to apply the combination of coatings is intricate, and ensuring it is properly completed can be an expensive undertaking. The pre-treatment of the fastening materials is even more important for ceramic coatings than for a traditional PTFE coating. Additionally, the ceramic coating Xylar 1 needs to be hardened at 400° C. After which the coating needs to be reactivated to ensure a proper bond with the Xylan 1070.
The above-mentioned surface treatments are included in our product list and have daily contact with the proper suppliers and receive shipments on an almost daily basis to ensure their constant availability. Even the more “exotic” processes, such as the Xylar/Xylan, are produced by us every day, though longer delivery times should be taken into account due to the extensiveness of the processes.
