The wood-b sed bo rds mostly bonded with ure -form ldehyde (UF )resin re the m in re sons of form ldehyde pollution of indoor ir.To m ster the curing mech nism of UF resin is the key for resolving the form ldehyde pollution problem.According to the tr dition l condens tion polymeriz tion theory, colloid l concept of UF resin, nd some experiment l nd production f cts, this p per discussed the form ldehyde content of UF resin, form ldehyde emission nd w ter resist nce of wood-b sed bo rds, nd the effects of mol r r tios nd c t lysts on the curing r te of UF resin, the existent problems of the tr dition l condens tion polymeriz tion theory, nd the colloid l concept for expl ining the curing mech nism of UF resin were cl rified .
