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.
The impact of coalescent type, coalescent concentration and latex type variables on film formation were investigated through the application of key statistical tools.
It has been demonstrated that a judicious choice of two HM-NSPs – one being weakly associative and the other being strongly associative – can provide the target rheology for allacrylic and styrene-acrylic-based waterborne coatings.
Excellent pigment stabilization and universal compatibility in solventborne, solvent-free and waterborne systems can be obtained with a single additive.
