Paints that dry by simple solvent hummer http://www.kejks.org evaporation contain a solid binder dissolved in a solvent; this forms a solid film when the solvent evaporates, and the film can re-dissolve in the solvent again. Classic nitrocellulose ford http://www.samomalo.com lacquers fall into this category, as do non-grain raising stains composed of dyes dissolved in solvent. Latex paint is a water-based dispersion of sub-micrometre polymer particles. The term \"latex\" in the context of paint simply means an aqueous dispersion; latex rubber (the sap of the rubber tree that has historically mercedes http://www.klinac.org been called latex) is not an ingredient. These dispersions are prepared by emulsion polymerization. Latex paints cure by a process called coalescence where first the water, and then the trace, or coalescing, solvent, evaporate and draw together and soften the latex binder particles and fuse them together into irreversibly bound networked structures, so that the paint will not redissolve in the solvent/water that originally carried it. Residual surfactants in the paint as well as hydrolytic effects with some polymers cause the paint to remain susceptible to softening and, over time, degradation by water. Paints that cure by oxidative crosslinking are generally single package coatings that when applied, the exposure to oxygen in the air starts a process that crosslinks and polymerizes the binder component. Classic alkyd enamels would fall into this category.
