Abstract
Abstract Water dispersible compositions containing hydrocarbon wax are described which are useful in preparing aqueous water repellent systems. Aqueous water repellent systems containing a hydrocarbon wax also are described. The water repellent system comprises an aqueous system comprising water, a saturated hydrocarbon wax, at least one oil-soluble metal salt of an organic carboxylic acid, at least one surfactant and at least one hydrocarbon solvent. A process for impregnating permeable substrates such as wood, cloth, concrete, rope, etc. with the water repellent system is also described. Penetration of the various components into the substrate is obtained by brushing, dipping, soaking, spraying or immersion at atmospheric pressure, at elevated pressures or under vacuum. The oil-soluble metal salt often is a fungicide. Moreover, additional components can be contained in the aqueous system such as insecticides, colorants, flame retardants, moldicides, wood stabilizing agents, etc.
