Abstract to:
Permeation through Polymer Latex Films made from Model Colloids.

On the grounds of cost, safe handling, and environmental acceptability, aqueous latex coatings are to be preferred to organic solvent based systems. These advantages outweigh the problems of greater energy requirements, arising from the higher latent heat of vaporisation of water, and poorer film properties such as lower gloss and greater permeability to pollutant gases. In spraying applications, latex can be the preferred choice, even when water is a potential solvent, because of the low viscosity and high solid loadings of the latex (or pseudo latex) formulation. The aim of this paper is to review briefly the background theories of film formation from polymer latices and to review results obtained for transport through films made from "model colloid" latices in relation to their morphology.
