striping effect. Depending on the quality of the surface of the specific wood-based panels, low application grammages can be realised. A highly smooth and even [...] contrast to the conventional thermoplastic EVA systems, these new formulations based on polyolefins allow to create adhesive bondlines with a degree of hardness [...] hot melt formulations do not contain water. Any possible swelling of the wood-based substrates is therefore prevented, resulting in a significantly improved smoothness
