Abstract
A release agent composition which is particularly suited for industrial applications such as preventing the adhesion of asphalt or concrete materials to surfaces such as truck beds, other containers, or equipment used in handling these compounds. The release agent composition includes lecithin in combination with a dispersing agent, particularly a propylene based glycol ether, a propylene based glycol ether acetate, an ethylene based glycol ether, or an ethylene based glycol ether acetate and mixtures thereof. The lecithin and dispersing agent are mixed with water to form an aqueous dispersion for application to surfaces.
