This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This Small Business Innovation Research Phase I project will address the problem of solvent-based primers and coatings on metals that require a conversion coatings on the substrate for adhesion and corrosion performance. Such primers also contain toxic chromate-containing anti-corrosion pigments. The objective of the project will be to formulate anti-corrosion primers and complete coatings ('supercoats' or self-priming coatings) for a wide range of metals, such as aluminum alloys, hot-dip galvanized steel and cold-rolled steel. Instead of using hydrophobic primers we will formulate coatings that are more hydrophilic but possess a highly hydrophobic metal-coating interface. Such coatings will essentially consist of water-dispersed resins, organofunctional silanes and nanoparticles. They will contain very little VOC and non-chromate anti-corrosion pigments. In this Phase I our objectives and technical results will be to, i) better understand the reactions between the components in the systems, such as resins and silanes, and how these interaction determine the properties of the system, and ii) to have at least one formulation that can be sprayed onto a bare metal and then forms a 100-µm one-step coating that meets certain performance criteria, such as adhesion and corrosion protection. The broader impacts of the project will be that this activity will enhance our scientific understanding of the mechanisms by which coatings protect metals and how anti-corrosion pigments work in such systems. The relationship between the hydrophilicity of the coating vehicle and the water-solubility of the pigment will be addressed in this project. The mechanism by which certain inhibitors protect metals, e.g., phosphates, is another focus of our study. This high-risk project will have considerable cost and environmental advantages. Potential customers for this technology are numerous. Examples are the aerospace industry (coatings for aircraft), automotive industry (car repair finishes and modification of the painting line in automobile manufacturing plants), wash primers for repair and touch-up, shipbuilding industry, the coil coating (steel) industry, and many others, representing a commercial value of at least $100 million. This technology has the potential to revolutionize the paint and coating industry. Its societal impact will be that workers in paint-manufacturing plants will no longer be exposed to vapors of organic solvents or to toxic chromate-containing materials.

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。该小企业创新研究第一阶段项目将解决金属上的溶剂型底漆和涂料问题，这些底漆和涂料需要在基材上进行转化涂层以提高附着力和腐蚀性能。这种底漆还含有有毒的含铬酸盐的防腐蚀颜料。该项目的目标是为各种金属，如铝合金、热浸镀锌钢和冷轧钢，配制防腐蚀底漆和完整涂层（“超级涂层”或自底涂层）。代替使用疏水底漆，我们将配制更亲水但具有高度疏水的金属涂层界面的涂层。这种涂料将基本上由水分散树脂、有机官能硅烷和纳米颗粒组成。它们将含有非常少的VOC和非铬酸盐防腐颜料。在第一阶段，我们的目标和技术成果将是：i）更好地了解系统中组分（如树脂和硅烷）之间的反应，以及这些相互作用如何决定系统的性能; ii）至少有一种配方可以喷涂到裸金属上，然后形成符合某些性能标准的100 µm一步涂层，例如粘附和腐蚀保护。 该项目更广泛的影响将是，这项活动将提高我们对涂料保护金属的机制以及防腐蚀颜料如何在此类系统中工作的科学理解。本计画将探讨涂料载体的亲水性与颜料的水溶性之间的关系。某些抑制剂保护金属的机制，例如， 磷酸盐，是我们研究的另一个重点。这一高风险项目将具有相当大的成本和环境优势。这项技术的潜在客户很多。例如，航空航天工业（飞机涂料）、汽车工业（汽车修理和汽车制造厂喷漆线的改造）、修理和修补用的清洗底漆、造船工业、卷材涂料（钢）工业以及许多其他工业，其商业价值至少为1亿美元。这项技术有可能彻底改变油漆和涂料行业。它的社会影响将是油漆制造厂的工人将不再接触有机溶剂的蒸气或有毒的含铬酸盐的材料。
