Claims5
A wood preservative which consists essentially of an aqueous solution containing from 5 to 40% by weight of a neutralized alkyd resin produced from phthalic acid or phthalic anhydride, glycerol and a saturated fatty acid and from 0.5 to 5% by weight of a water insoluble fungicidal or insecticidal active ingredient selected from the group consisting of 2,5-dimethylfuran-3-carboxylic acid N-methoxy-N-cyclohexylamide, tributyl-tin benzoate, tributyl-tin naphthenate, gamma-hexachlorocylohexane, pentachlorophenol laurate, 2-methoxycarbonylamino-benzimidazole or a mixture of these active ingredients wherein the solvent system consists essentially of water.
A process for preserving wood from attack by fungi or insects, wherein the wood is treated with an aqueous solution containing from 5 to 40% by weight of a neutralized alkyd resin produced from phthalic acid or phthalic anhydride, glycerol and a saturated fatty acid and from 0.5 to 5% by weight of a water insoluble fungicidal or insecticidal active ingredient selected from the group consisting of 2,5-dimethylfuran-3-carboxylic acid N-methoxy-N-cyclohexylamide, tributyl-tin benzoate, tributyl-tin naphthenate, gamma-hexachlorocyclohexane, pentachlorophenol laurate, 2-methoxycarbonyl aminobenzimidazole or a mixture of these active ingredients wherein the solvent system consists essentially of water.
