Abstract:
A curable coating composition comprising the following components:(a) a polymer containing reactive functional groups; (b) a curing agent containing functional groups which are reactive with the functional groups of (a); and (c) an acidified dispersion of exfoliated silicate prepared by (1) contacting a layer silicate having interlayer cations with an acid or acid solution to exchange the interlayer cations; (2) intercalating the acidified layer silicate of (1) with an exfoliating polymer; and (3) exfoliating the intercalated layer silicate of (2) by applying shear to the intercalated silicate/acid mixture, wherein said exfoliating polymer is compatible with the polymer (a) and the curing agent (b).
