Printing
A wide range of adhesives are used in the production of books. From products based on dispersion adhesives (PVAC, EVA), hot melt adhesives (EVA, APAO, PUR) to glutin adhesives.
Dispersion adhesives
In the woodworking industry, PVAC dispersion adhesives are mainly used, divided according to water resistance into classes D1 to D4. Polyurethane aqueous dispersions are used in the cladding (3D) of furniture doors, with heat reactivation of the adhesive. In the case of cold cladding of wooden profiles, EVA-based dispersions are used.
Polyurethane hot melt adhesives
Polyurethane adhesives (prepolymers) are used in the wood industry, especially for bonding more difficult to bond materials where high water resistance and heat resistance of the bonded joint is required. Depending on the type of materials used, one-component or two-component products are used for bonding.
Hot melt adhesives
Fusible adhesives are used to edge wood materials with paper, veneer or ABS edge. The application is carried out on mechanical edging machines that have the possibility of melting the adhesive to the application temperature. EVA, APAO and PUR based hot melt adhesives are used to sheath the profiles. The choice of the appropriate adhesive depends on the substrate material used for the cladding, as well as the water and heat resistance requirements of the product.
