Surface Technology

Profile

 

Coatings protect surfaces, are functional or simply decorative. Committed to the environment, the researchers from the Surface Technology department develop paints and adhesives on the basis of vegetable oils, sugars, lignin and waste materials.

We carry out research for our customers on the entire value chain of wood coatings and adhesion, including the synthesis of binders, formulation and application of coatings. Method development of weather-related aging processes, standard tests and damage analysis complete our profile. We examine the products in their entirety and are therefore your competent research partner at every stage of the development.

 

Research Focuses

 

Wood coatings

We develop functional coatings which are durable and pleasant to the touch and which are suitable for indoor and outdoor wood surfaces. We specialize in conventional dispersions, reactive systems and UV-curable coatings.

 

Printing inks

We develop innovative printing inks on the basis of renewable raw materials for diverse application purposes and find alternatives to harmful constituents of printing inks.

 

Adhesives

We develop binding agents for adhesives for wood and wood-based materials. Our focus is placed upon the synthesis of acrylate and polyurethane-based binders, the production of water-based dispersions and the application of bio-based source materials.

 

Bio-based polymers

We develop low-solvent/solvent-free and water-soluble binders on the basis of sugars, vegetable oils and lignin for wood paints, glass and plastic coatings as well as in adhesives. 

 

Damage analysis

We perform damage analyses on coated wood, wood adhesions, wood-based materials and solid wood. This requires a combination of practical experience and specific scientific methodology.

 

Aging, weathering

We develop methods for practicable prediction in the weather-induced aging of coatings. Furthermore, we also offer standardized tests concerning natural and accelerated weathering.

The majority of industrially-manufactured products contain chemicals on the basis of petrochemical raw materials. In the growing bio-economic society, biochemical raw materials are increasingly coming into focus as climate-friendly alternatives. For industrial application, these must not only be ecologically and sociopolitically harmless, but must also be available in large quantities. We are developing concepts and technologies for this purpose. A particular focus is thereby being placed upon the material conversion of recycling wood.
