Patent

CA 2079657

There is disclosed a solid composition of polyglycidyl compounds having a molecular weight of less than 1500, which composition consists of one or more than one solid polyglycidyl compound and altogether not less than 5 % by weight of one or of a mixture of more than one polyglycidyl compound, which compound or mixture is normally in liquid form, said amount being based on the total amount of all polyglycidyl compounds in the composition, which composition contains the said solid polyglycidyl compounds or at least part of the said solid polyglycidyl compounds in form of one or a mixture of more than one solid mixed phase, which solid mixed phase or mixture of more than one solid mixed phase essentially comprises the total amount of the polyglycidyl compounds which are normally in liquid form as additional component or components. Preferably the compositions are solid solutions of a solid polyglycidyl compound, typically diglycidyl terephthalate, and a further polyglycidyl compound which is normally in liquid form, for example triglycidyl trimellitate or triglycidyl trimesate. The compositions are suitable hardeners for powder coating compositions based on carboxyl-terminated polyesters.
