Abstract
A clear air drying coating composition adapted for the coating of wood to preserve its freshly prepared appearance is disclosed in which a solution of an unsaturated oil-containing resin in a solvent medium containing at least 50% of mineral spirits has stably dispersed therein from about 13 to 63 parts of granulated paraffin wax having an average melting point in the range of 50.degree. C.-70.degree. C. and from 0.5 to 20 parts of a transparent ultraviolet-absorbing pigment per 100 parts of the resin, the pigment being preferably yellow to maintain the natural color of the freshly prepared wood.
Claims15
A clear air drying coating composition adapted for the coating of wood to preserve its freshly prepared appearance comprising, a solution of:
- (1) an unsaturated oil-containing resin in (2) a solvent medium containing at least 50% of mineral spirits, (3) from about 13 to 63 parts of granulated paraffin wax having an average melting point in the range of 50.degree. C.-70.degree. C. per 100 parts of said resin stably dispersed in said solution, and said solution having dispersed therein (4) from 0.5 to 20 parts of a transparent ultraviolet-absorbing pigment per 100 parts of said resin.
A clear air drying coating composition adapted for the coating of wood to preserve its freshly prepared appearance comprising, a solution of an unsaturated oil-containing alkyd resin having an oil length of 35% to 65% in a solvent medium consisting essentially of mineral spirits, from about 53 to 63 parts of granulated paraffin wax having an average melting point in the range of 50.degree. C.-70.degree. C. per 100 parts of said resin stably dispersed in said solution, and said solution having dispersed therein from 1 to 6 parts of a transparent yellow hydrated ferric oxide pigment per 100 parts of said resin.
