Water-borne industrial coatings in western Europe, are predicted to have an average annual growth rate of nearly 7.5%. In 1987, this sector had a value of $650 million. Much has been written about the resin types used in this area, whether they be acrylics, vinyl, alkyd, urethane, epoxy- or polyester based. Less has been presented concerning the practical advantages and uses of the many additives and extenders used in these systems. This conference was devised to review a representative cross-section of these additives to both explain their practical application and also to underline some of the basic formulation principles involved in water-borne coating technology. Products considered include urethane and polysaccharide-based rheology modifiers, microbiocides, corrosion inhibitors, co-solvents and coalescing agents, cross-linking agents, antifoams and polymeric additives and extenders. Each material represents a separate area of technology and it is hoped that the following papers will afford a greater understanding of the complex interactions which occur when these materials are formulated into water-based coatings.
