In his opening remarks Robson Storey, symposium chair, announced a name change for the event, which will now be called the Waterborne Symposium. This year's event presented a new expanded theme, "Advances in Intelligent Coatings Design." According to Storey, the program will retain its emphasis on waterborne, high solids and powder coatings, but will also address other contemporary themes including stimuli-responsive coatings, bio-based and renewable coatings and high-throughout methodologies for formulation. The 28 papers presented at this two day event provided a variety of information on these cutting-edge technologies.
At the Best Paper Awards ceremony Rob Storey presented the Elias Singer Outstanding USM Student Paper Award to Micah Black for "Auto-oxidation study of model fatty acid-functionalized acrylic copolymers."
The presentation provided a description of these next generation products. "These products reduce the minimum film formation temperature of dispersion polymers as or more efficiently than traditional coalescing solvents," said Galgoci. "In addition, they provide improved wetting and lower foam properties to the coatings. Low-VOC waterborne coatings that employ CS technology perform similarly to their higher-VOC counterparts."
The Shelby F. Thames Best Paper Award was presented to Jeanne Courter of Cytec for "Formulating industrial wood coatings with a novel formaldehyde-free crosslinker to replace conventional aminoplast crosslinkers."
On the regulation side, Ronald Hill of the American Solvents Council presented "Photochemical reactivity–a new paradigm for VOC regulation." According to Hill, current VOC regulations focus on reducing the mass of volatile organic compounds emitted from various applications, but there is a more effective and efficient way to reduce the contribution of VOC emissions to ground-level ozone formation.
"Reactivity-based approaches which distinguish between more reactive and less reactive VOCs can be important in areas where VOC control is key to reducing ozone concentrations," said Hill. He explained how an emerging concept, photochemical reactivity, can significantly increase coating formulation options and improve regulatory strategies directed at VOCs. "Reactivity-based approaches provide formulators of coatings with a multitude of formulation options, enabling the industry to retain important product attributes, while achieving and/or exceeding targeted reductions in ozone creation potential," Hill continued. "The use of photochemical reactivity approaches provide formulators with greater flexibility to meet product performance criteria because there are many lower reactivity solvents to choose from that provide the properties necessary for the particular application."
