The nature and type of adhesive used in manufacture of composites depend on the end use of the composites.We plan to use urea formaldehyde resins for our wastepaper based composites.Any alternative or suggestions.
Urea formaldehyde resins are widely used but tend to decompose in hot humid locations. Ligands derived from wood are sometimes used in rigid constructions. Low and medium temperature melting glues of waxy types are used in hand crafts. Best advice is to use a glue that is recommended by the manufacturer for the purpose you have in mind.
