Abstract
An emulsion composition to coat a substrate that includes a barrier-forming material, water; an organometallic compound, and at least one thickener is described. The composition may further include a material such as talc. Articles, including ductile pipes, coated with this material are also described. A method of increasing the drying rate of a composition applied to a substrate to form a coating that includes application of the emulsion composition and drying the composition to form a coating layer. Also included are methods of forming a coating that exhibits a reduced incidence of blocking or pull-off, comprising applying the emulsion composition to a substrate and drying, whereby the coating layer formed exhibits a reduced incidence of blocking or pull off relative to conventional asphalt emulsion coatings.
