A new generation of hybrid waterborne alkyd dispersions has been specifically designed and developed to provide the best protection on horizontal and some vertical wood surfaces.
Part one of this article discusses the theory of optimizing applied hiding and new techniques used to characterize applied paint films to determine the influence of rheology on application.
More companies are adding and/or expanding their portfolios with biobased waterborne alternatives that offer the formulator/end user another benefit without sacrificing performance.
The use of the pigment encapsulating acrylic binder in exterior applications can not only decrease the amount of TiO2 at the same hiding level, bringing possible cost reduction, but can also help to improve exterior durability such as dirt pick up resistance, tint retention and efflorescence resistance.
Independent corrosion tests have shown this is a successful conductive polymer-based anti-corrosion coating technology and the first non-chromate coating that has out-performed hexavalent chromate coatings.
New products are being developed to meet the challenge of delivering low- and zero-VOC offerings, including specialty resins, coalescents/plasticizers, water-based and energy curable colorants, foam control and silicone products.
