2. Collagen Modified Hardener for Melamine-Formaldehyde Adhesive for Increasing Water-Resistance of Plywood
One of the very important technological operations in woodworking industry is gluing. The aim of this work was preparation of hardener for melamine-formaldehyde (MEF) adhesives suitable for gluing of plywood. Commercial hardener was modified by biopolymers (waste animal polymers). Glued joints were expected to be classified as resistant to water in class 3.
