Ultra-Low VOC Waterborne Alkyd Coatings with Exceptional Corrosion Resistance

Ultra-Low VOC Waterborne Alkyd Coatings with Exceptional Corrosion Resistance
Available for download

Solventborne alkyd resins are widely used in industrial coatings because of their excellent gloss, good adhesion and wetting properties as well as excellent compatibility with other resin types. In many regions, however, the consumption of alkyds is diminishing as stringent environmental regulations drive the coatings industry towards lower volatile organic compound (VOC) systems. Waterborne (WB) coating systems have replaced some solventborne (SB) alkyd paints; however, these WB coatings typically do not offer the same performance as their solventborne counterparts.

In many regions, however, the consumption of alkyds is diminishing as stringent environmental regulations drive the coatings industry towards lower volatile organic compound (VOC) systems. Waterborne (WB) coating systems have replaced some solventborne (SB) alkyd paints; however, these WB coatings typically do not offer the same performance as their solventborne counterparts. A new technology has been developed to disperse traditional high viscosity, short oil alkyds with minimal surfactant and no polymer modification. These attributes enable pigmented waterborne alkyd coatings with comparable properties to those of conventional solventborne alkyd coatings. For example, short oil alkyds can be dispersed into water and formulated into coatings with <10 g/L VOC, excellent gloss and comparable/better corrosion protection (300 hr @ 1 mil thickness) to solventborne alkyd coatings.

Often when a polymeric flooring system fails, the cause of the problem is unknown. Forensic testing is used to determine the cause of failure while eliminating other potential causes. A basic understanding of the approach to a forensic investigation and the types of testing used will help aid in correcting the problem so future failures and project costs are reduced.

Corrosion is a major concern for all materials during their service lives. In particular, salts such as sodium chloride (NaCl) are known to promote corrosion and detrimentally affect coating performance. Understanding how NaCl affects water uptake into a film and its interactions with corrosion-inhibiting pigments is important for developing the next generation of anticorrosive coatings.
