Abstract
Adhesive bonds between materials, such as woods having porous surfaces, formed by polymerizing in situ alphacyanoacrylate monomers, are accelerated in curing and strengthened by precoating the surfaces to be joined with a solid mixture of alkaline or basic accelerator, such as sodium or potassium hydroxide or sodium borosilicate spheres of micro-size, combined in a chalkable calcareous binder to form a light but adhesive permeable coating, before the monomeric adhesive is applied. The latter permeates in part through the light precoating to bond into the wood and is accelerated in its polymerization so that it is not excessively absorbed into the porous substrate, resulting in a bond of superior strength.
