Private label




Diffutherm's research and development focuses on the development of coatings, adhesives and sealants, for the automotive aftermarket and other branches of industry.

A specialized, dynamic team conducts research into both the optimization of existing products and the development of new ones. Among the team's key tasks is the implementation of customer recipes using our existing infrastructure.

The development and implementation take place on the basis of customer-oriented questions or market developments in the areas of quality assurance and environmental protection.

Corrosion tests are performed to investigate the products' corrosion properties. Tensile and shear stress measurements on both wet and dry material provide information concerning the performance and processing of various materials. With the aid of a stone chip resistance tester and/or linear taber abraser the wear resistance of the various products can be measured.

Temperature and environmental effects on our products are simulated using various methods, such as UV and salt spray tests.

Many analyses are performed both continuously and cyclically. Ultimately, the aim of the analyses and tests is to achieve the best possible product and production process at the lowest cost price within the parameters of the customer's requirements.
