One type of birch plywood production by-product: plywood sanding dust (PSD) and virgin polypropylene (PP) composites adhesive activity was investigated. To improve of the WP (PP+40 wt.% PSD) composites sheets as overlay bonding strength against birch plywood surface and water resistance of these laminated systems the industrially produced WPC material was modified with maleated polypropylene wax (MAPP) additives. These studies showed possibility of the usage of presented by-product as an excellent reinforcement for PP based wood plastic composites and addition of the coupling agent (MAPP) gives the considerable increase of adhesive activity of the used WPC. Due to the presence of MAPP (up to 4%) significantly increases not only adhesive strength of the laminates but also water resistance of the laminated sandwich specimens. As the example adhesive bonding strength could reach 2,74 N/mm2 and increases up to 4 times to compare with unmodified WPC adhesives.
