The abbreviation PFAS is "doing the rounds" and possible restrictions or bans on perfluorinated and polyfluorinated alkyl compounds are also affecting the coating sector. This is because PTFE belongs to the PFAS group and high-performance PTFE coatings have become almost indispensable in sealing technology. This is why a coating specialist has developed a PFAS-free bonded coating and is offering an adequate replacement for premium PTFE coating systems on seals even before any restrictions have been decided.

The planned PFAS restrictions - a hotly debated topic. Especially in the plastics industry, but of course also within the coatings industry. In the latest issue of DICHT! 3.2023 we were allowed to comment on this. As we are naturally heavily affected in the painting and coating technology sector, because many of the bonded coatings available contain PFAS, we are taking a proactive approach to this issue.

We have now invested heavily once again and have been securing our energy needs this year with our own photovoltaic and liquid gas systems. This gives us and our customers the necessary security and stability. Since the beginning of the Ukraine conflict, however, we have felt more clearly than ever how energy-intensive industrial coating is. Read more about how we keep production costs stable with our new equipment.

The German contract coating company APO started small and now owns the largest number of Rotamat coaters of any business in the world. The company currently operates ten machines of this kind and coats around one billion parts per year. Walther Trowal and APO worked closely together to develop the Rotamat so that it could coat plastic parts as well as metal ones.

11.2019 The use of plasma for the treatment, cleaning and refinement of component surfaces has long been a technical standard in industry. Low-pressure plasma is indispensable, especially when dealing with the coating, bonding or lacquering of elastomeric and other polymer components. However, not all plasma units can achieve the same effects within comparable times. The new and patented plasma equipment technology from APO GmbH provides savings potentials for the cleaning and coating of components.

019 To achieve the required PWIS/LABS free condition or PWIS/LABS conformity components need to be cleaned. In particular, the cleaning of elastomeric components, such as sealing elements, is an especially challenging task. This presentation explains the failure mode caused by PWIS/LABS and gives a brief summary of the VDMA specification 24364.
