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.
