Abstract
Abstract A high solid coating composition curable at ambient temperature, causing no air pollution in use, which comprises the mixture of: (1) alkyd resin prepared from (a) saturated aliphatic or aromatic polybasic acids or their anhydrides, (b) polyhydric alcohols and (c) unsaturated vegetable oils or unsaturated vegetable oil fatty acids, and (II) metallic alcoholates and/or chelate compounds thereof. Some portion of said alkyd resin can be replaced by modified oils or butadiene polymers.
