Powder coated mesh helps university ace its gold LEED certification
FOCUS low-volatile organic compound (lowVOC) resins that cure fast and hard, eliminating the need for baking or forcedrying of metal parts. They are designed for original equipment manufacturers (OEMs), including those with limited or no baking capabilities, that coat metal parts used in agricultural equipment, locomotives and railcars, outdoor furniture, light poles, exterior electrical cabinets and hardware, trailers and shipping containers.

Bio-based Chemicals: Greener Paints Can Improve Coverage The need to meet sustainability agendas, combined with the benefits offered by bio-based raw materials, drives the paints and coatings industry's increasing interest for newer renewable technologies. The industry is exploring the use of bio-based raw materials to meet the demand for products that have better environmental performance. Bio-based raw materials can improve carbon and life-cycle performance of paints and coatings as well as provide reduced toxicity, higher purity and better water solubility. Other advantages of renewable raw materials include the potential for unique functionality and the ability to reduce supply chain risk as well as the amount of new carbon released. A number of companies are working towards the production of key paint and coating ingredients. For instance, BioAmber and Ecoat are evaluating pentaerythritol alkyd (PA) resins

containing bio-based succinic acid (SA) and found that bio-based SA can replace between 20–35% of the PA and retain performance. Myriant has also used bio-SA in producing a line of developmental 100% bio-based polyester polyols with more price stability. Elsewhere, Elevance is exploring the use of octadecanedioic acid as a bio-based raw material for new additives and resin systems for paints and coatings. Corbion is developing a process for the microbial production of 2, 5-furandicarboxylic acid for the manufacture of various coating resins. Meanwhile, Cargill and Novozymes are developing a bio-based process for acrylic acid and 3-hydroxypropionic (3HP). NatureWorks previously launched a high purity, polymer-grade lactide for the manufacture of amorphous coatings, adhesives, copolymers, printing toners, surfactants and emulsions.

Powder coated mesh helps university ace its gold LEED certification Frank A. Cassell Hall, the first sustainable building on the University of Pittsburgh at Greensburg campus, received Gold LEED certification from the United States Green Building Council (USGBC). Designed by Pittsburgh-based Forty Eighty Architecture, Cassell Hall is nestled in a steep hillside along the south bank of Slate Run. Its environmental sustainability and aesthetic features— including woven wire mesh infill panels—accentuate its connection to the natural world. The Banker Wire infill panels and angle iron frame were used on the building's exterior ramp and plaza, where they allow for the uninterrupted transmission of natural light into the building. "For this installation, we wanted a railing system that was custom and transparent, but more durable and easier for our client to maintain than glass. The FPZ-16 mesh with a powder-coated finish met that criteria,'' says Kent Suhrbier, principal at Forty Eighty Architecture. Its powder-coat finish complements the warm hues of the building's interior, natural light and surrounding flora. The designers had virtually unlimited color choices but ultimately settled on a warm neutral. Harrison Horan, vice president at Banker Wire, had been working with the architectural design firm so he knew that
C OAT I N G S the chosen finish would have to meet the requirements for the university to get its LEED certification. This would mean contributing to LEED credits in the recycled content category. Horan says that after the structures were made, they were outsourced for an eco-friendly powder coated finish to Milwaukee-based B&K Powder Coating Corp. The custom coater used TCI Powder Coatings' zinc-rich primer which was topcoated with a super-durable neutral finish color.

Powder coatings - back on the fast track A long period of innovation in powder coatings came to a halt at the turn of the century, primarily due to economic and market changes. Promising new end uses now require developments in formulation or application. These include the use of plastic substrates and large objects which cannot be cured in ovens. Innovation is being driven by a number of external forces. Most prominent are new generations of fabricated goods. As the transport industry strives to continually improve fuel economy by incorporating weight reductions into its products, more and more manufactured goods are being designed as moulded plastics. These moulded articles are replacing traditional sheet metal forming products and cast metal parts. Conventional powder coatings are typically applied electrostatically to an earthed conductive substrate, but as these moulded parts are non-conductive, powder application is problematic. Researchers have found that the application of a conductive agent to plastic moulded parts is the most consistent and economical option. One of the challenges in finishing plastic substrates is establishing adhesion between the coating and the plastic. High HDT (heat deflection temperature) plastics tend to provide a good surface for adhesion; though the presence of mould-release compounds can compromise adhesion and therefore must be carefully assessed. With lower HDT plastics, especially those based on polyolefins, it is difficult to achieve a good bond between the powder coating and substrate. These materials possess a high surface tension which inhibits the wetting of the plastic by the molten powder coating. Hence pre-treatment or conditioning schemes are sometimes required to reduce the surface tension.
