Wood coatings

We develop functional coatings for interior and exterior use. Antimicrobial, hydrophobic, oleophobic and pleasant to the touch surfaces form the focus of our development work. We specialize in conventional dispersions, reactive systems and UV-curable coatings.

The main focus in wood paint development is placed upon binder synthesis. This requires knowledge of polymerization techniques which are also used in industrial applications (polyaddition, polymerization and polycondensation) as well as procedures for the production of dispersions (primary and secondary dispersions). For the synthesis of polyesters, polyurethanes and polyacrylates, renewable raw materials from the oil and saccharide chemical industry, for example 1,3-propanediol-based polyurethane dispersions, UV-curable itaconates and sugar acrylates, are being increasingly used. In the subsequent formulation and application of the paints, the primary focus is formed by the technical properties of the paints, such as the improvement of durability, hydrophobia, oleophobia, substrate adhesion, scratch resistance and gloss.

A unique characteristic which distinguishes us is that we examine the value chain holistically. This is essential if structural property relationships are to be comprehensively examined and discussed. Many years of experience and expertise in synthesis, formulation, characterization and testing of coatings is complemented by the wealth of knowledge traditionally generated at the Fraunhofer WKI concerning the substrate wood.
