Title: Evaluations of Wetting and Dispersing Additives for Use in Waterborne Anti-Corrosive Paint
Over the last few years the protective coatings industry has seen an increased demand for high performance waterborne coatings in the field of corrosion protection. Market drivers such as “Sustainability”, “Greenability”, and ongoing regulatory and environmental concerns continue to force coatings producers to look for other viable options to replace conventional solvent borne technologies. By their very nature waterborne systems require elaborate additive packages so that they can achieve acceptable levels of performance when compared to traditional technologies.
On one hand, wetting and dispersing additives are required to achieve proper pigment and filler dispersions, coating processability, and proper hiding and other film properties. On the other hand it can be said that waterborne wetting and dispersing additives potentially bear the risk of increasing hydrophilicity of the paint film which may potentially have negative impact on paint film barrier properties such as, early water and moisture resistance, water uptake, and corrosion resistance.
The topic of this paper is a new wetting & dispersing additive based on novel chemical technologies, which allow for improvements in durability, anti-corrosion, and adhesion properties of the coating along with improved processing characteristics.
