Abstract (EN):
Melamine-formaldehyde resins represent an important class of aminoplastic resin and are made by the
reaction of formaldehyde with mainly melamine.
Melamine-formaldehyde resins are used as adhesives for plywood and particleboard for use in humid
and exterior conditions and are also used for the impregnation of paper sheets in the production of selfadhesive overlays for the surface of wood-based panel products and of self-adhesive laminates [1].
During the last decade the interest in using raw materials based on bio-renewable resources for
synthetic polymers and composite materials increased largely [2]. Recent developments in eco-efficient
bio-based adhesives for wood bonding include the use of tannins, lignin, proteins, and carbohydrate
derived natural binders.
The main goal of this work is the partial replacement of melamine in melamine-formaldehyde resins by
glycerol, yielding a stable resin with potential for use in impregnated paper based laminates.
