How to Improve the Scratch Ressitance of UV Cured Wood Coatings ?

Scratch resistance is one of the key properties for industrial wood coatings, both for furniture and parquet flooring. Different techniques can be used to evaluate the performances of a coating and results can be strongly affected only by changing the measuring tool used. This paper will explain the different methods available to assess the scratch resistance and their relevancy. Then, the role played by of all the different components of a UV formulation on the scratch resistance will be shown oligomer, monomer, photoinitiator, and then additives like nanoparticules.
