Bonding with wood
The main use for HMAs (hot-melt adhesives) in woodworking is to fix veneer to chipboard, fiberboard or similar materials in the furniture industry. The advantages of these adhesives based on polymer/resin blends include a rapid setting, reduced compression section and avoidance of drying areas, indefinite shelf life and low toxocity. The miscibility of the polymer/resin blend is one of the key factors for a proper selection, having great influence on the practical performance of HMAs. The HMA was formulated with an EVA copolymer, a hydrocarbon C9 resin and various compatibilizing agents. These compatibilizing agents are tackifying resins compatible with the EVA polymer. Transparency, tensile properties, SAFT (shear adhesion failure temperature), and thermal-thermomechanical properties were determined. By the use of a compatibilizing agent, a HMA formulated with EVA and C9 Norsolen resin was obtained which is transparent at room temperature without impairing thermal resistance. Without the use of a compatibilizing agent, a transparent blend with poor application properties was obtained. The formulation with a compatibilizing agent yielded cohesion and adhesion in combination with transparency.
