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.
Claims12
A high solid coating composition curable at ambient temperatures and characterized by a solid content of at least 80% at 70 KU viscosity which comprises the mixture of:
- I. 100 parts by weight of alkyd resin having an oil length of not less than 65%, resin acid value of not more than 7, Gardner-Holdt viscosity (25.degree. C) of not more than Z and solid content of not less than 90% which is prepared by the reaction among (a) saturated aliphatic or aromatic polybasic acids or their acid anhydrides, (b) polyhydric alcohols, and (c) unsaturated vegetable oils or unsaturated vegetable oil fatty acids, and
- Ii. 1 to 10 parts by weight of at least one aluminum alcoholate or chelate thereof.
