The University of Southern Mississippi’s School of Polymers and High Performance Materials held its 38th Annual Waterborne Symposium February 28 – March 4 at The Astor Crowne Plaza in New Orleans, LA. This year’s Symposium, which had 267 attendees, featured 53 speakers on subjects ranging from UV technology, pigments, additives, waterborne systems, corrosion and a state of the industry special update.
The Symposium began with a state of the industry update from Phil Phillips of the Chemark Consulting Group. His presentation, “State of the Industry…Where Will the Coatings Technologies be in 2015?” offered a broad view of the global coatings market. “The global paint and coatings market reached an estimated $89.5 billion through the end of 2010,” said Phillips. “This global market figure is forecasted to increase with a modest compound annual growth rate (CAGR) of 3.1 percent for the period of 2010 to 2015 and reach $104.2 billion by the end of 2015.”
“Waterborne paint and coating technologies are the largest environmentally friendly single technologies globally,” he continued. “The current market is an estimated $28.9 billion in 2010, and is expected to grow to $37.7 billion in 2015, a compound annual growth rate of 5.3 percent. Forty-three percent of the current value is represented by a combination of powder, waterborne and emerging systems. By 2015 they will represent over 50 percent.”
The plenary lecture, “Advances in Living/Controlled Polymerization in Waterborne Systems: New Opportunities in Designing Latexes with Tailored Microstructure and Properties” was given by Michael Cunningham of Queen’s University in Ontario, Canada.
“Historically, finely tuned control of the molecular weight distribution in free radical polymerizations has posed a significant challenge,” said Cunningham. “Because of the stochastic nature of the polymer chain growth chemistry, distributions are typically broad with both very short and very long chains being produced. Living/controlled radical polymerization (L/CRP) provides a relatively straightforward means to prepare polymers with narrow molecular weight distributions, specialized architectures such as di- or tri-block copolymers and functionalized polymers. While L/CRP was originally perceived as a somewhat esoteric, complex and expensive process, increased understanding of the polymerization chemistry coupled with recent developments, particularly in waterborne systems, have created a myriad of opportunities for commercial exploitation of L/CRP chemistry in the coatings area.”
This year there were sessions related to waterborne, nano, emulsion, additives, corrosion, UV and pigments. The waterborne session began with “Waterborne Polyurethane Coatings used in Direct to Metal Applications” presented by Peter Schmitt of Bayer MaterialScience. “Polyurethane chemistry has been utilized to produce a myriad of different coating products,” said Schmitt. “Recent advances have been made in polyurethane dispersion chemistry for use in direct to metal coatings.” He then went on describe the coating properties related to direct to metal applications and discussed the results.
Linda Adamson of the Dow Chemical Company presented “Enabling High Performance Solvent-free Low Odor Architectural Coatings: A Comprehensive Approach.” “The technology pathways that lead to formulating high performance house paints with low odor and no added cosolvents or volatile coalescents are separate and can be at odds with each other,” said Adamson.
Eliminating strong odors from house paint, such as ammonia and some solvents does not by itself result in zero/near zero VOC. In addition, simply reducing the VOC content of binders, rheology modifiers and other paint components to very low levels, does not automatically result in low odor coatings. Until now performance compromises were often needed to achieve both targets simultaneously. Adamson discussed a comprehensive approach, bringing together the latest advances in odor reduction technology and the newest developments in binder design for zero/near-zero VOC coatings. “The careful combination of these advances results in solvent-free systems that achieve very low odor, without compromise in performance,” she said.
In addition to the main technical program, the Waterborne Symposium featured a Student Poster Session and Technology Showcase consisting of eighteen tabletop technical exhibits, including displays from Evonik Degussa Corp., Huntsman Advanced Materials, Clariant and Buhler.
The Symposium concluded with an awards presentation for the best papers and student poster. The Best Student Poster Award was presented to James Goetz of the University of Southern Mississippi for his poster titled, “Effect of Crosslink Density on Barrier Properties in UV Cured, Liquid Crystalline Elastomer Networks.”
The Technical Excellence Award was given to Brian Bammel of Henkel Corporation for his paper “Novel Non-Chrome Thin Organic Hybrid Coating for Coil Steels.”
The Shelby F. Thames Best Paper Award was presented to Linda Adamson of Dow Chemical Company for her paper “Enabling High Performance Solvent-free Low Odor Architectural Coatings: A Comprehensive Approach.”
Next year’s Symposium will be held February 13-17 at the New Orleans Marriott.
The School of Polymers and High Performance Materials at The University of Southern Mississippi has issued a call for papers for presentation at the 39th Annual International Waterborne Symposium, February 13-17, 2012 in New Orleans. Papers should relate to new and emerging technologies related to materials, processes, production, characterization, application and markets in the field of surface coatings. All papers should be original and represent recent advances in coatings science and related disciplines. Title, abstract and author’s names (speaker’s name underlined) should be submitted by mail, fax or e-mail no later than Aug. 15 to the School of Polymers and High Performance Materials, The University of Southern Mississippi, Box 10063, Hattiesburg, MS 39406-0063; 601.266.4475; Fax: 601.266.6265; E-mail: firstname.lastname@example.org; Web: www.psrc.usm.edu/waterborne.
