Abstract
Lowering of formaldehyde emission from wood based panels by modification of polycondensation adhesives with natural fillers, additives and activators. Modification of polycondensation resins were directed to urea-formaldehyde adhesives with the application in woodworking industry. Fibril proteins of skin, mainly collagen and keratin, polymer polyphenolic molecules of vegetable tannins are significant and perspective biopolymers for selected technical applications e.g. bonding and lowering of formaldehyde from UF bonded materials. Tested modifications confirmed the influence of additives on viscosity of adhesive mixtures and their applicability for gluing of wood based panels with enhanced bonding quality and formaldehyde emissions.
