Claims19
A deep penetrating water-resistant sealer composition comprising a mixture of (1) an aromatic hydrocarbon solvent, (2) a chlorinated hydrocarbon solvent, (3) an aliphatic hydrocarbon solvent, and (4) a hydroxy-substituted polyorganosiloxane, the amount of the aromatic hydrocarbon solvent being under 20% by volume, the amount of the chlorinated hydrocarbon solvent being under 65% by volume, the amount of the aliphatic hydrocarbon solvent being under 40% by volume, and the amount of the hydroxy-substituted polyorganosiloxane being under 20% by volume.
A process for preparing a deep penetrating water-resistant sealer composition which comprises adding up to 20% by volume of a hydroxy-substituted polyorganosiloxane to up to 20% by volume of an aromatic hydrocarbon solvent, adding to the resulting mixture up to 65% by volume of a chlorinated hydrocarbon solvent and then adding to the resulting mixture up to 40% by volume of an aliphatic hydrocarbon solvent.
A process for treating a surface to make it resistant to water, metal ions and chloride ions penetration which comprises applying to the surface a liquid sealer composition comprising a mixture of (1) an aromatic hydrocarbon solvent, (2) a chlorinated hydrocarbon solvent, (3) an aliphatic hydrocarbon solvent, and (4) a hydroxy-substituted polyorganosiloxane, and allowing the resulting coating to air dry.
