ABSTRACT:
The invention concerns new, liquid compositions, stable in storage at room temperature, based on polymers containing acid anhydride groups as a binder, said compositions crosslinking under the action of heat and characterized by containing dispersed, solid, powdered, anhydride reactive crosslinker which, through the application of heat, can crosslink the binder containing anhydride groups under solidification. The features of these compositions are their low toxicity, low crosslinking temperatures and good mechanical strength of the crosslinked product. The invention also concerns a method of their manufacture and their use as heat curing coatings, potting compounds, sealants and adhesives.
