Coatings play a key role in determining the durability and performance efficiency of wind energy units despite accounting for a small fraction of the total cost of a new wind-turbine unit. The global market for coatings used in wind-energy applications has been estimated to be $170 million in 2008. It is expected that the wind-turbine coatings market will reach $240 million by 2012, including blades, towers, and components. Advancements in coatings technology are essential for attaining the desired level of performance and efficiency in wind-energy units. Epoxy and polyurethane primers are available to be used on composite blades along with specially designed topcoats. PPG is one of the manufacturers that has developed PSX® 700, an engineered siloxane for steel components and AUE-50000, and erosion-resistant polyurethane coating for turbine blades.

Various manufacturers have focused their efforts in the development of novel and unique coating materials and films that can protect, improve, and power solar cells. DuPont introduced a new DuPont™ PV5300 sheet based on ionomer, which is more stiffer, stronger, and resistant to moisture intrusion, and is undergoing weathering and durability tests on different solar cells. Professor Yi Cui and colleagues at Stanford University have developed a nano-coating that can reduce reflection in solar cells. Konarka Technologies is marketing a line of solar panels for use in various portable charging applications based on its Power Plastic® material. Plextronic's Plexcore® PV is a ready-to-use ink system consisting of a photoactive ink and custom-designed hole transport ink that are solution processable.

The present market size for all polymer-based roof coating is likely to be around $500-$550 million by The ChemQuest Group. The majority of these coatings are acrylic formulations with urethanes, silicones and exposies. The Dow Chemical Company and BASF are the leading resin suppliers for the field applied segment, where the strong growth rate for acrylics in particular is in large part driven by the political attention that coo roof coatings have received in 2009, specifically from the DOE and Secretary Steven Chu. At least one new entrant into the roof coating market is hoping to get a share of the cool coatings market. United Environment & Energy is developing a smart roof coating that can respond changes in temperature. Initial tests have been positive with Asphalt shingles coated with the new material having been found to reduce the roof temperature in warm weather and increase the roof temperature in cooler weather as compared to a traditional cool roof.

Nanomaterials are being increasingly used in coating materials despite the uncertainty regarding the future regulation of nanomaterials. New nanomaterials-enhanced coatings enable and improve mar and scratch resistance, provide durable UV protection, and act as alternatives to chromium and zinc for corrosion protection. The White House Emerging Technologies Interagency Policy Coordination Committee (ETIPC) has developed a set of principles specific to the regulation and oversight of applications of nanotechnology to guide the development and implementation of policies at the agency level. California, Massachusetts, Pennsylvania, and South Carolina are some of the states that have targeted nanomaterials as chemicals of concern and are evaluating the appropriate steps to take. The most successful applications of nanocoatings have focused on three improved properties, abrasion resistance, UV resistance and corrosion protection.

The green building movement continues to have a significant influence on the paint and coatings industry. Formulators and their suppliers develop products and processes designed to meet the standards of the many groups that certify construction materials and the buildings made with them. Here, CoatingsTech presents the views of a number of raw materials suppliers and coating manufacturers on how the green building movement has affected the industry in general, and what influence it has had on their specific product development and manufacturing activities. © 2013 by ACA.

Sourcing the regulatory issues that were prevalent in the year 2011 in the coatings manufacturing industry are discussed. It is found that in this year most companies have invested much of their R&D resources into cutting costs or finding alternative materials. The year has been the period that has experienced more approvals of alternative materials than at any other time. DuPont has announced that it will be expanding titania capacity at existing facilities in the US and will be adding a production line in Mexico, with the work to be completed by 2014. Many architectural paints will be required to remove the coalescent Texanol from their formulations. Producers of colorants for use with architectural and industrial maintenance coatings will need to reformulate their products to be in compliance with California's South Coast Air Quality Management District (SCAQMD) 113 rule that takes effects in 2014.

Coatings suppliers are working to displace acrylics with lower cost and more readily available resins such as VAE. Arkema Emulsion Systems says that alternative binder technologies may provide a significant improvement in the cost/performance ratio that will allow formulators to meet both performance and value targets in their end products. Dow Coating Materials (DCM) has focused on process technology to the waterborne traffic paint market, which can help to lower a paint's dependence on the level of acrylic latex binder. OMN+OVA Solutions also offers zinc-free acrylic alternatives for floor coatings such as non-zinc polymer that is very effective in achieving high performing polishes. Dow offers an acrylic resin, called RHOPLEX™ HG-706 acrylic emulsion, which addresses the susceptibility of low-VOC acrylate paints to produce softer films with block resistance problems, especially in tinted systems.

Additives have a significant impact on performance and functionality, although they represent only a small fraction of the total content of a paint or coating formulation. The impact of additives on a formulation can vary depending on the application, but every component makes a difference. Green biocidal additives should be characterized by favorable human toxicology profiles. They should not cause substantial impact to the environment at use levels and should not be sensitizers. Silicon additives are absolutely necessary components of greener formulations. They can improve the longevity of paint, thus reducing the repainting frequency. They are often multifunctional, making it possible to replace two or three current additives with one. Surfactants and related additives, defoamers, dispersants, and other compounds that affect performance based on surface chemistry, are the easiest class of additives to target for developing green alternatives, since their chemical structures are well suited for synthesis from naturally derived materials.

The building of stronger relationships between various links in the supply chain is an approach that contractors, raw material suppliers, coating manufacturers and architects find to be highly beneficial. The most significant perceived risks facing the coatings industry for both manufacturers and suppliers are raw materials pricing and availability, lagging consumer demands and regulatory pressures. Diana Strongsky, vice president of R&D for the Coatings Division of the Sherwin-Williams Company, says that the intense focus of the public on the short term availability of raw materials has led to a deepening of some paint manufacturer/supplier relationships and a weakening of others. She emphasizes that the solution to overcoming these challenges is innovation. The changes in coating formulations as the result of regulations and the growing green building movement are also having an impact on the relationships between members of the supply chain.

As with most coating end-users, customers in the aerospace and military sectors look for ways to lower cost and increase the ease of applicability of coating technologies while maintaining the desired level of performance. Direct-to-metal (DTM), or self-priming, coatings have provided such benefits when used in light- to medium-duty general applications. However, there have been significant challenges with their use in the more demanding aerospace and military applications. Here, CoatingsTech details the advantages that can be gained with the use of DTM coatings, such as increased coating application efficiency, lower costs, reduced labor demand, and lower energy use. Such benefits are examined in the context of the recent advances in DTM technologies and the challenges that still remain.
