Session III: Sustainable solutions
Chair: Kenneth M. Perry, Technical Director, NAFTA Automotive Coatings, BASF CorporationMonday Afternoon 2:00 p.m. – 5:50 p.m.
Breakout Room 217 C/D
Sustainability is about living and working in ways that meet and integrate existing environmental, economic and social needs without compromising the well-being of future generations. This session provides examples of what the coatings industry has in store for this increasingly important issue, for instance, lowering VOC emissions, using renewable resources, substituting ecologically harmful substances and implementing highly eco-efficient procedures. | ||
3.1 2:00 – 2:30 p.m. New Resins for Low VOC Waterborne Trim and Maintenance Coatings Dennis St. Laurent*, Robert Equi, Cytec Industries This paper will present the newest advances in waterborne alkyd technology and the performance characteristics of these resins in a number of application areas. Recent developments allow for the design of new high performance resins for diverse end-uses such as decorative paints, industrial primers, top coats and waterborne stains. The newest waterborne alkyd resins provide formulators the capability to design coatings able to meet the SCAQMD VOC limits put into effect in July 2007. North American coatings companies will have the flexibility to use one resin to formulate products across the range of VOC limits expected to be legislated by January 2010. Comparative performance data will be presented on a range of interior and exterior gloss and semi-gloss trim coatings and light duty maintenance coatings. | ||
| 3.2 2:30 – 3:00 p.m. Low odor, VOC-free, Renewable Coalescents Designed for Latexes Used in Very Low VOC Paints Anbu Natesh*, Vishnu Shah, Cognis Corporation Two of the most important contributors to VOCs in low VOC paints are ethylene or propylene glycol and coalescents. We have found that specific high purity esters of fatty acids and their blends can be utilized to provide very low odor, VOC-free, renewable coalescents to enhance the performance of latexes used in very low VOC paints. A methodology for determining ideal coalescent levels, resultant formulation cost reduction and significant performance enhancement over popular, non-renewable coalescents will be demonstrated. | ||
| 3.3 3:00 – 3:30 p.m. Optimizing Durability in Aqueous Semitransparent Deck Stains Greg Monaghan, Rohm and Haas Company Semitransparent stains have been traditionally designed to erode uniformly from a deck, leaving a surface which can be recoated with little preparation. The built in erosive failure mode often means that semitransparent deck stains typically have a relatively short life and that decks need to be restained fairly frequently. The development of a new class of acrylic stain binder designed for longer durability will be presented along with the results of an experimental design to evaluate nano size UV blocking pigments and encapsulated UV absorbers. This new acrylic binder also gives improved performance over new decking substrates such as copper azole treated pine, cedar and redwood and meets possible future environmental initiatives regulating APEO surfactants, metal driers and volatile organic compounds. 3:30 – 4:00 p.m. Networking: Refreshments & Coffee Break | ||
| 3.4 4:00 – 4:30 p.m. Novel Low VOC Soya Polyester Acrylic Hybrid Coating Madhukar (Duke) Rao*, Richard Tomko, Pete Mackulin, James Marlow, Sherwin Williams Company The ever tightening environmental regulations restricting commonly used solventborne coatings are forcing coating formulators to gravitate to waterborne coatings based on latex emulsions. Such coatings have their challenges in meeting satisfactory performance in some industrial coatings. This paper presents a novel oxidatively crosslinked hybrid dispersion binder which has a distribution of hard and soft segments from hydrophobic/hydrophilic functionalities in a "green" soybean oil diluent. Low VOC waterborne coatings formulated from this hybrid dispersion exhibit unique performance attributes of interest to coatings formulators. An industrial maintenance coating formulated at < 100 g/l exhibited fast dry, excellent adhesion to metal, excellent early moisture resistance, excellent hydrolytic resistance, high gloss, as well as a good chemical and corrosion resistance. The coating has water clean-up and open time similar to latex based coatings. Similarly, a low VOC penetrating clear coating over wood exhibited good penetration and barrier properties. | ||
| 3.5 4:30 – 5:00 p.m. Drying Oil Additive for Foam Reduction Michael Van De Mark*, Elizabeth Abram, Missouri S&T Coatings Institute A modified drying oil developed as a coalescent aid was evaluated as a foam destabilizing agent. Addition of part of the oil based coalescent aid in the grind reduced the amount of foam equivalent to a conventional defoaming agent. The additive was evaluated by surface tension as well as foam stability in a newly developed test which will also be presented. The additive was effective in several different resin systems. | ||
| 3.6 5:00 – 5:30 p.m. Closed Loop Recycling as a Sustainability Solution for the Paint & Coatings Industry Stephanie Baker, KW Plastics The paint and coatings industry is literally throwing hundreds of millions of dollars in valuable scrap plastic material into the waste streams every year. There is an opportunity for the industry to be sustainable while saving real dollars. Sustainability is certainly a hot topic and paint manufacturers are spending a great deal of time and money researching how they become more “green“. True sustainability must affect (1) social, (2) environmental and (3) economical change. Recycling is the sensible sustainability solution for all three. There are the obvious social and environmental rewards for recycling. However, the economic impact and savings that a closed loop system creates can also affect a company’s bottom line. For the first time, the industry can control their packaging costs. | ||
| 5:30 – 5:50 p.m. Poster Previews 5:50 – 7:30 p.m. Full Poster Session/ Networking: After Work Party In conjunction with the poster session, conference delegates, chairpersons and speakers are invited to meet in a relaxed atmosphere immediately after the end of the oral conference program on Monday, June 2, 2008. The After Work Party of the American Coatings Conference is an ideal opportunity to renew and strengthen contacts, cultivate business relationships, exchange latest news and participate in discussions, as well as enjoy refreshments, a beer and music. | ||
