High Performance Fillers in Wood Coatings and Decorative Melamine Films

The usage of micronized fillers in UV curing parquet lacquers is not common due to lack of transparency. Nevertheless there is the tendency, to use fillers more and more to increase scratch resistance and for cost reduction reasons.

Nano additives are able to increase scratch resistance but the usage cannot be recommended in terms of economic efficiency. Besides characterisation of hard and soft High Performance Fillers used, formulations for transparent micro-fillers on the basis of polyurethaneacrylate and melamin resin have been developed and tested.
