Abstract
Abstract Coating compositions in the form of a gel capable of being broken up for application to a suitable substrate by application of a relatively small shearing force at a relatively small shearing rate. The coating composition of this invention employs a rheological control system comprising an amine-modified montmorillonite clay, a swelling agent therefore, and a nonvolatile oleaginous agent for wetting the clay. The invention is particularly adapted for pigment-containing coating systems.
