Abstract

553,754. Resinous condensation products. BRITISH INDUSTRIAL PLASTICS, Ltd. (American Cyanamid Co.). Dec. 12, 1941, No. 16085. [Class 2 (iii)] Curing catalysts for acid-curing thermosetting resins have the general formula wherein R is hydrogen, -COOH or -O-S-X and # C X is a carbocyclic or heterocyclic radical. Acid curing thermosetting resins are defined as those which cure only under acid conditions and also those which cure under either acid or alkaline conditions, e.g. condensation products of aldehydes with urea, thiourea, dicyandiamide, aminotriazines such as melamine and phenols or mixed resins e.g. urea-melamine-formaldehyde and urea-thiourea-formaldehyde. Suitable catalysts are benzoyl-or phthaloyl-mercapto benzothiazole and thio-#-naphthyl benzoate. Fillers such as wood pulp, wood flour, cotton linters and clay, colouring matters, mould lubricants such as zinc stearate, modifying agents such as starches, gums, alginates and casien and plasticizers such as toluene-sulphonamides, alkyd resins and polyhydric alcohols may be added. The compositions may be used as moulding powders, coating-compositions and adhesives, or in impregnating and laminating.
