A friable micro-particle comprises a solid matrix and at least one additional solid material dispersed with the solid matrix, wherein the additional solid material is releasable form, or exposable from within the solid matrix to initiate or boost cure of a curable material. A micro-particle comprising a solid matrix in which at least one reactive component of a cure system for a curable composition is held in solid solution in the matrix as well as a curable composition, a method of bonding and methods for making the micro-particles are also disclosed. The additional material may be one or more metal salts, onium salts, nucleophic amines, a cure catalyst or a cure accelerator. The solid matrix may be comprised of polysaccharide, polyvinyl alcohol, polyethylene, polypropylene or combinations thereof.
