Heat curable composition.

摘要

A curable powder composition comprising two or more separate powdered reactive components is provided with a thin coating of binder on the powder particles under conditions which leave the particles separate from one another. This composition can be rendered cohesive, e.g. by compression, to form self-supporting but surprisingly flexible sheets or other articles of the curable adhesive, while retaining the particles in discrete form within the sheet to retain the desirable balance of storage life against curing performance derived from the particulate form of the reactants.
