Gloss Level of HDF Finished with Different Numbers of Layers and Hardened with UV Hg-Ga Lamps of Selected Power

A key feature of varnish coatings on furniture surfaces is their optical properties, which often determine customers’ purchase choices. Furniture may be produced using various boards, are much cheaper than wood-based materials. For finishing, among others, UV-cured products used. The aim this study was to the effect different types HDF amount basecoat and topcoat applied, number layers, lamp powers used for hardening gloss obtained UV technology. tested with a photoelectric apparatus. An auxiliary parameter in assessment surface roughness, measured Mitutoyo SJ-210 Analysis variance (ANOVA) obtain results. Statistical considerations showed that power lamps, interactions between them had greatest impact gloss, followed by layers. In general, coating decreased decrease range 120–60 W/cm an increase applied.
