Coating compositions and methods providing a high build, fast drying, fast hardening non-amine containing aqueous latex binders are provided, wherein the coating composition is applied to a substrate at a wet film thickness to about 15 mils that ensure drying times of less than 10 minutes. The binder requires the use of at least one specific coalescent solvent with both anionic and non-anionic surfactants.

Fast drying aqueous amine free coating composition(s)

The present disclosure provides latex compositions manufactured using a combination of reactive surfactants. The compositions are useful as road marking materials.

Latex polymerization using a combination of reactive surfactants for traffic markings

The latex polymer compositions of the present invention exhibit latent crosslinking properties. Latent crosslinking in the polymers takes advantage of the fast interaction between the anionic latex charge and the cationic charge associated with polyfunctional amine crosslinkers. Once the latex is coated onto a substrate, the volatile base evaporates and the groups react to form a crosslinked coating with improved wash-off properties.

Controlled crosslinking of latex polymers with polyfunctional amines

Disclosed are aqueous coating compositions containing an anionically stabilized polymer, one or more polyfunctional amines acting as crosslinking agents, and a volatile base. Coating compositions can further include one or more additional copolymers, which may or may not be anionically stabilized, and/or additional additives, including pigments, defoamers, pigment dispersing agents, thickeners, surfactants, and combinations thereof. By incorporating one or more polyfunctional amines, such as those comprising recurring units derived from the reaction of one tri-glycidyl moiety and a single di-, or tri-functional amino monomer, or a combination of mono/bi, mono/tri, mono/tetra, bi/bi, bi/tri, bi/tetra, tri/tri, tri/tetra, and tetra/tetra functional amino monomers with a bi- or tri-glycidyl moiety, water wash-off resistance of the coating compositions which comprise paint formulations, can be increased.
