A study of properties of POSS-modified varnish coatings UV-cured on a wood surface

Research was carried out in a new topic area related to the quality of lacquer finishes on wood surfaces, such as furniture or floor elements. Selected results are presented relating to basic mechanical properties of composite varnish coatings modified with a selected commercial POSS compound, photo-cured on the surface of a chosen wood species. The test results obtained for two groups of varnish coatings differing in the varnish binder used (oligoether or oligoester) pointed to various effects of POSS modification of the varnish compositions and UV-cured coatings. These effects were dependent on the functional property considered as well as the content of POSS nanofiller in the varnish composition. In general, the presence of selected POSS molecules in the UV coating structure improved its abrasion and linear scratching resistance, but did not improve – or even slightly reduced – the adhesion of the coating to the wood surface.
