Abstract
A low odor aqueous coating composition is described. The composition is a waterbased latex coating composition that includes a binder component with at least one copolymer and a neutralizing component. The composition dries in less than about 10 minutes at a temperature between about 5 to 35° C. and a relative humidity between about 30 and 95% with a pH of 9.5 or less. The coating composition can be used for applications such as road marking and coating exterior surfaces, where use of a low-odor coating is desired.
Claims55
A low odor aqueous coating composition for road marking, comprising:
- a binder component comprising a first resin component comprising an acrylic polymer derived from one or more ethylenically unsaturated monomers and a second resin component comprising a polyamine, thereby forming a copolymer or copolymer blend;
- and
- a neutralizing component,
- wherein the pH of the composition is less than 9.5 and wherein the coating composition dries in less than about 10 minutes at a temperature between about 5 to 35° C.
A method for making a low odor water-based road marking paint, comprising:
- providing a first resin component comprising a latex polymer derived from one or more ethylenically unsaturated monomers;
- providing a second resin component comprising a low molecular weight polyamino-functional polymer;
- combining the first and second resin components to form a copolymer blend;
- providing a neutralizing component;
- and
- adding the neutralizing component to the copolymer blend, wherein the pH of the low odor composition is less than 9.5.
A low odor aqueous coating composition for coating an exterior surface, comprising:
- a binder component comprising a first resin component comprising an acrylic polymer derived from one or more ethylenically unsaturated monomers and a second resin component comprising a polyamine, thereby forming a copolymer or copolymer blend;
- and
- a neutralizing component,
- wherein the pH of the composition is less than 9.5 and wherein the coating composition dries in less than about 10 minutes at a temperature between about 5 to 35° C.
