Abstract
This invention provides film-forming compositions, including but not limited to polishes, coatings, adhesives and inks, comprising a at least one acrylic or vinyl acetate polymer or copolymer as a film-forming ingredient and, as the plasticizer, a blend in specified proportions of a) the benzoate of a 6-carbon monohydric alcohol, b) diethylene glycol dibenzoate and c) diethylene glycol monobenzoate.
Claims30
A film-forming composition comprising
- A) at least one polymer selected from the group comprising:
- (1) homopolymers and copolymers of esters of acrylic and methacrylic acids;
- (2) said copolymers wherein a portion of repeating units are derived from at least one acid selected from the group consisting of acrylic and methacrylic acids;
- (3) copolymers of styrene and at least one member selected from the group consisting of esters of acrylic and methacrylic acids;
- and
- (4) homopolymers and copolymers of vinyl acetate;
- B) a mixture of benzoic acid esters in an amount effective for optimizing film properties in a film formed from said film-forming composition, the mixture of benzoic acid esters comprising:
- (1) from about 15 to about 20 weight percent, based on the total weight of the mixture of benzoic acid esters, of an ester having a formula PhCO(O)R1, where Ph is a phenyl radical and R1 is a linear or branched alkyl radical containing 8 carbon atoms.
- (2) from about 60 to about 65 weight percent, based on the total weight of the mixture of benzoic acid esters, of diethylene glycol dibenzoate, and
- (3) from about 20 to about 25 weight percent, based on the total weight of the mixture of benzoic acid esters, of diethylene glycol monobenzoate.
A polish composition for flooring surfaces formed from wood, stone and vinyl polymers, wherein films applied using said composition have a combination of hardness, leveling, high gloss, and recoatability in combination with resistance to soiling and spotting by water, and wherein said composition comprises:
- A) at least one polymer selected from the group comprising:
- (1) homopolymers and copolymers of esters of acrylic and methacrylic acids;
- (2) said copolymers wherein a portion of repeating units are derived from at least one acid selected from the group consisting of acrylic and methacrylic acids;
- (3) copolymers of styrene and at least one member selected from the group consisting of esters of acrylic and methacrylic acids;
- B) a mixture of benzoic acid esters comprising
- (1) from about 15 to about 20 weight percent, based on the total weight of the mixture of benzoic acid esters, of an ester having a formula PhCO(O)R1, where Ph is a phenyl radical and R1 is a linear or branched alkyl radical containing 8 carbon atoms,
- (2) from about 60 to about 65 weight percent, based on the total weight of the mixture of benzoic acid esters, of diethylene glycol dibenzoate, and
- (3) from about 20 to about 25 weight percent, based on the total weight of the mixture of benzoic acid esters, of diethylene glycol monobenzoate.
A method of making a film forming composition comprising blending a polymer with a mixture of benzoic acid esters,
- wherein the polymer includes at least one polymer from the group comprising homopolymers and copolymers of esters of acrylic and methacrylic acids;
- copolymers having a portion of repeating units derived from at least one acid selected from the group consisting of acrylic and methacrylic acids;
- copolymers of styrene and at least one member by selected from the group consisting of esters of acrylic and methacrylic acids;
- and homopolymers and copolymers of vinyl acetate,
- wherein the mixture of benzoic acid esters comprising from about 15 to about 20 weight percent, based on the total weight of the mixture of benzoic acid esters, of an ester having the formula PhCO(O)R1, where Ph is a phenyl radical and R1 is a linear or branched alkyl radical containing 8 carbon atoms, from about 60 to about 65 weight percent, based on the total weight of the mixture of benzoic acid esters, of diethylene glycol dibenzoate, and from about 20 to about 25 weight percent, based on the total weight of the mixture of benzoic acid esters, of diethylene glycol monobenzoate.
