Abstract
Abstract The present invention relates to modified non-Newtonian colloidal disperse systems exhibiting improved thickening power, particularly when diluted. These compositions are useful as high-solids, thermosetting caulks, molding compositions, extruding compositions and the like, but are particularly suitable for use as high solids thermosetting coating compositions. These coating compositions are heat-stable and sag-resistant. The compositions of this invention comprise a mixture of (B) at least one non-Newtonian colloidal disperse system comprising (B-1) solid metal-containing colloidal particles, (B-2) a liquid dispersing medium, and (B-3) at least one organic compound which is soluble in said dispersing medium, the molecules of said organic compound being characterized by a hydrophobic portion and at least one polar substituent; and (C) at least one hydrogenated block copolymer of a vinyl aromatic monomer and an aliphatic conjugated diene. Optionally, the compositions also contain (D) a substantially inert, normally liquid diluent. The invention also relates to methods of coating metal surfaces with the compositions of the invention described above as well as compositions comprising mixtures of neutral and/or basic metal salts of organic acidic materials and the copolymers (C) described above.
