(thixotropic paint). A paint formulation that has a semisolid or gel consistency when undisturbed, but that flows readily under the brush or when stirred or shaken. After removal of the stress, it becomes stiff again and has little tendency to spill, drip, or run. The thixotropic quality is obtained by the carefully controlled reaction of a relatively small proportion of a polyamide resin with an alkyd resin vehicle.See Thixotropy.
