Jocelyn (Josie) Gruver received a Ph.D. and M.S. in Chemistry from Cornell University, Ithaca, NY and a B.S. degree in Chemistry from Saint Mary’s College, Notre Dame, IN. She joined The Dow Chemical Company in 2010 and has since spent time in both Architectural and Industrial Coatings. The first few years were focused on R&D, primarily concentrated on emulsion polymer synthesis for industrial coatings. Josie holds several patents from her work in Industrial Coatings. In 2013, Josie transferred to the Coatings Technical Service Department and has focused on supporting new binder technology for the interior and exterior marketplace.  Josie’s first role in the Technical Service Department was in Architectural Wall and Masonry Binders group. Currently, Josie is an Associate Technical Service Manager in the Specialty Binder group. 


Wooden decks have become popular home features that add outdoor living space and are one of the best returns on investment. However, if not properly maintained and protected from the elements, their initial beauty can quickly decline. Since the typical homeowner does not always take the appropriate steps to protect their decking, a new category of thick-film coatings has emerged in order to refurbish wood decking rather than replace it. While the current commercial deck coatings are quite different chemically, they must overcome similar performance challenges. Proper preparation of the wood substrate is key for minimizing premature coating failures, which adds a new challenge as this market continues to grow in the DIY segment. Results from real world exposures on dimensionally unstable substrates clearly convey the challenges of this market. Data will be presented that shows how binder variations can improve performance properties such as adhesion, tensile-elongation, and crack/blister resistance, which leads to better durability in real world exposure studies.
