Acrylic resin dispersion

An acrylic resin dispersion consists of a fine distribution of synthetic resin particles in water. The microscopic resin particles are suspended in the water, they are not dissolved. As the water evaporates the particles become closer together. Once they touch each other they merge to form a continuous synthetic film. A synthetic resin dispersion in water is milky white and once dry is colourless and transparent.

A common name for a dispersion-binder is latex. The term latex, however, is usually used when referring to a synthetic dispersion that is made not based on an acrylic resin, but based on a P.V.Ac. (polyvinyl acetate) resin or a derivative of this. An important difference is that latex is not alkaline resistant or much less so than acrylic resin.
