Abstract:
An adhesive composition for use in precoating a threaded fastener, which comprises:(A) a suspension comprising a mixture of:(A1) at least one polymerization accelerator;(A2) at least one monomer having at least one polymerizable double bond at a terminal thereof or in a side chain thereof;(A3) at least one substance which becomes acidic when dissolved in water selected from the soup consisting of a phosphorus acid ester, a phosphoric acid ester, an aliphatic or aromatic carboxylic acid containing a carboxyl group at a terminal thereof and having a double bond in its molecule, an anhydride of an aliphatic or aromatic carboxylic acid containing a carboxyl group at a terminal thereof and having a double bond in its molecule, a carboxyl group-containing (meth)acrylate, a maleic anhydride and a maleic acid; and(A4) an aqueous binder which is water-solubilized by alkali salting, has an emulsifying capability and which, due to the presence of said at least one substance (A3), produces a water-insoluble layer to form the particle portion of the suspension; and(B) microcapsules containing at least one polymerization initiator.
