Claims15
A biodegradable tenacious oil-containing composition comprising a mixture of a biodegradable lubricant oil and a resinous component said component being selected from the group consisting of colophonium-containing biodegradable resins, colophonium and mixtures thereof, the weight ratio of said oil to said resinous component being within a range selected from the group consisting of:
- (a) about 40 to about 80 weight parts of said oil per about 60 to about 20 weight parts of said resinous component;
- and
- (b) about 70 to about 90 weight parts of said oil per about 30 to about 10 weight parts of said resinous component.
A method for lubricating a motor saw chain comprising applying to said chain a lubricating effective amount of a composition comprising a mixture of a biodegradable lubricant oil and a resinous component selected from the group consisting of biodegradable colophonium containing resins, colophonium and mixtures thereof, the weight ratio of said oil to said resinous component being within the range:
- about 40 to about 80 weight parts of said oil to about 60 to about 20 weight parts of said resinous component.
A method of rendering a mold releasable from a molded article cast therein comprising applying to a surface of said mold that will be in contact with said article, a substantially uniform coating of a release-effective amount of a mold release agent comprising a mixture of a biodegradable lubricant oil and a resinous component said component being selected from the group consisting of biodegradable colophonium-containing resins, colophonium, and mixtures thereof, the weight ratio of said oil to said resinous component being within the range of about 70 to about 90 weight parts of said oil per about 30 to about 10 weight parts of said resinous component.
A lubricated motor saw chain coated with a lubricating effective amount of a tenacious biodegradable composition comprising a biodegradable lubricant oil component and a resinous component selected from the group consisting of biodegradable colophonium-containing resins, colophonium and mixtures thereof wherein the weight ratio of said oil to said resinous component is within the range of about 40 to about 80 weight parts of said oil per about 80 to about 40 weight parts of said resinous component.
A releasable mold article comprising a mold coated on a surface contacting the article cast therein with a substantially uniform coating of a mold-release effective amount of a composition comprising a biodegradable oil component and a resinous component, said resinous component being selected from the group consisting of biodegradable colophonium-containing resins, colophonium and mixtures thereof, therein the weight ratio of said oil to said resinous component is within the range of about 70 to about 90 weight parts of said oil per about 30 to about 10 weight parts of said resinous component.
