Sažetak
The oriented strand boards (OSB) and particle boards (PB) have a wide range of applications because they are cheaper material than solid wood and most other engineered wood products. OSB is used in interior and exterior, while particle boards are mostly used in the interior. Furthermore, particleboards are commonly used in furniture production, while OSB is mostly used as sheathing for roofs and walls, subfloors, and single-layer flooring. Surface finish of OSB and PB with coating materials are very rare, and there is limited information about the interaction between coating and surface of OSB and PB. Moreover, OSB is most used as a non-finish board, while particle boards are mostly covered with overlay paper or foil. The objective of this paper was to study the interaction of different coating systems with OSB and PB surfaces. Three types of the board surface preparation were tested: raw, sanded and reheated in press. After surface preparation, board samples were finished with water-based and solvent-based coating systems. Methods for characterization of boards surfaces were hardness of a material, wetting angle and surface roughness. On finished samples, dry film thickness, adhesion, water absorption, and their aesthetic properties were measured. The results of this research showed significant differences between coated and uncoated samples and between different coating systems. Also, aesthetic properties were improved on most of the samples, and surfaces have a wide range of applications.
