Title: (EN) COMPOSITION AND METHOD FOR CURING A RESORCINOL RESIN
(FR) COMPOSITION ET PROCEDE DE DURCISSEMENT D'UNE RESINE RESORCINOL
Abstract: front page image
(EN) A catalyst curing system or hardener for resorcinolic resins, such as resorcinol-formaldehyde or phenol-resorcinol-formaldehyde resins including methylolurea. The methylolurea may be used in combination with oxazolidine in ratios ranging to 5:95 to 95:5, by molar basis. The hardener cross-links the resin which permits reduction or "fuming" of formaldehyde as well as control of gel times of the resulting adhesive. The hardener of the present invention if of particular utility in adhesives for use in the forest products industry.
