Coating systems comprising dioxolane film-forming agents
Dioxolane compound film-forming agents are formulated into surface coating compositions such as paints and varnishes, in particular industrial, graphic and architectural paints, and serve as coalescence agents and/or drying retardants.
1. A coating composition comprising at least one dioxolane compound having the formula (I):
in which R 1 and R 2 , which may be identical or different, are each a hydrogen atom or an alkyl, alkenyl or phenyl radical, and n is an integer 1, 2, 3, 4 or 5, and
a nitrocellulose, a polyester, or a cellulose acetate butyrate (CAB), or
a polyurethane, an epoxy, an acrylic, a melamine, or a phenolic-formulation, or
a vinyl, a vinyl-acrylic, a straight acrylic, or a styrene acrylic formulation.
2. The coating composition as defined by claim 1 , where, in formula (I), R 1 and R 2 are methyl, ethyl, n-propyl, isopropyl or isobutyl radicals.
3. The coating composition as defined by claim 1 , where, in formula (I), n is 1 or 2.
4. The coating composition as defined by claim 1 , said at least one dioxolane compound comprising 2,2-dimethyl-1,3-dioxolane-4-methanol.
5. The coating composition as defined by claim 1 , said at least one dioxolane compound comprising 2,2-diisobutyl-1,3-dioxolane-4-methanol.
6. The coating composition as defined by claim 1 , wherein said composition is formulated as a paint or varnish.
7. The coating composition as defined by claim 1 , wherein said composition is formulated as an industrial, graphic or architectural paint.
8. The coating composition as defined by claim 1 , wherein said composition is a water-based formulation.
9. The coating composition as defined by claim 1 , wherein said composition is a solvent-based formulation.
10. The coating composition as defined by claim 1 , wherein said at least one dioxolane compound comprises from 0.1% to 10% by weight of said composition.
11. A method of coating a composition, the method comprising applying the composition as defined by claim 1 to the surface of said composition.
12. A method of making a composition, the method comprising adding to a coating formulation at least one dioxolane compound having the formula (I):
in which R 1 and R 2 , which may be identical or different, are each a hydrogen atom or an alkyl, alkenyl or phenyl radical, and n is an integer 1, 2, 3, 4 or 5,
wherein the coating formulation is based on
a nitrocellulose, a polyester, or a cellulose acetate butyrate (CAB) system, or
a polyurethane, an epoxy, an acrylic, a melamine, or a phenolic system, or
a vinyl, a vinyl-acrylic, a straight acrylic, or a styrene acrylic system.
13. A method of retarding the drying of a coating composition, the method comprising adding to a coating formulation at least one dioxolane compound having the formula (I):
in which R 1 and R 2 , which may be identical or different, are each a hydrogen atom or an alkyl, alkenyl or phenyl radical, and n is an integer 1, 2, 3, 4 or 5,
wherein the coating formulation is based on
a nitrocellulose, a polyester, or a cellulose acetate butyrate (CAB) system, or a
polyurethane, an epoxy, an acrylic, a melamine, or a phenolic system, or
a vinyl, a vinyl-acrylic, a straight acrylic, or a styrene acrylic formulation
and applying said composition to a substrate.
