Performance tests for coatings, lacquers, paints, and corrosion protection

Performance tests for coatings, lacquers, paints, and corrosion protection

In-Depth and Thorough Performance Tests in Fully Equipped Labs

Coatings perform differently in different situations. Some applications – for example those on ship hulls– need to be fully water-resistant. Others – for example required in chemical plants – have to withstand the applicable chemicals. Coatings applied on outdoor objects have to be colorfast and withstand sunligth and rain for long periods of time, over the course of many years. Often several factors, and standards have to be taken into account for different coatings, lacquers, and paints; for example, the protection against corrosion.

To fully ascertain whether a specific coating is suitable for specific objects or purposes, TÜV Rheinland offers several tests and test methods to measure the performance. The protective properties, visual appearance, degradation speedcan be tested. Based on our thorough performance tests, manufacturers can demonstrate the level of quality of their products. Buyers can make better decisions on which product is the right choice for their object and purpose. And suppliers can gain better market access to new markets with products suited to local requirements and standards.

TÜV Rheinland employs all manner of pragmatic testing methods and has in-depth knowledge and expertise of the tests and the sector. Ask our experts. We are glad to help.
