This Small Business Innovation Research Phase I project is designed to prepare and evaluate novel biobased corrosion protection coatings derived from modified soy oil that quickly cures upon exposure to atmospheric moisture yielding smooth protective films. This cure mechanism is based on the well known room temperature vulcanization of the reactive silicone and is applied here by grafting reactive silane onto the unsaturated fatty acid residues of the oil triglycerides. This approach provides a convenient one-component package and does not require reactive diluents, UV or oxygen for cure initiation. It does not incorporate alkyds or require epoxidized soy oil. Preliminary results show that crosslinking occurs relatively fast without requiring any volatile coalescing agents and the films are completely cured. Good adhesion to stainless-steel was observed and physical properties (hardness, tensile strength, elongation, etc.) of the coatings are expected to be easily controlled by the concentration of the grafted silicone component. The presence of reactive silane is particularly suitable for corrosion protection since it acts as a moisture scavenger as well as improving the adhesion with the metal surface. It is anticipated that successful completion of this work will replace petroleum-based materials with biobased materials in corrosion protection technology.The broader impact/commercial potential of this project is to provide permanent, organic coatings derived from renewable resources to offer clean technologies to the public. These biobased coatings are targeted for corrosion-prevention applications such as gas and liquid transmission pipelines, construction rebar for bridges and buildings, industrial equipment, etc. Corrosion of metallic structures has a significant impact on the US economy. Results of a NACE study (2002) shows that the total annual estimated direct cost of corrosion in the U.S. is a staggering $276 billion - approximately 3.1% of the nation's Gross Domestic Product. Successful implementation of Phase I & II of this project will have the following technical, commercial, environmental and economical impacts: improved corrosion protection and ease of application, low capital investment, reduction in VOC/HAP and carbon footprint, preservation of fossil fuel resources, reduction in corrosion related costs to the industry, and creation of up to an additional five jobs for sales, manufacturing, and technical support of this newly developed product.

该小型企业创新研究第一阶段项目旨在制备和评估源自改性大豆油的新型生物基防腐蚀涂层，该涂层在暴露于大气水分后快速固化，产生光滑的保护膜。该固化机理基于众所周知的反应性硅酮的室温硫化，并且在此通过将反应性硅烷接枝到油甘油三酯的不饱和脂肪酸残基上来应用。这种方法提供了一种方便的单组分包装，并且不需要活性稀释剂、UV或氧气来引发固化。它不包含醇酸树脂或需要环氧大豆油。初步结果表明，交联发生相对较快，而不需要任何挥发性聚结剂和膜完全固化。观察到对不锈钢的良好粘附，并且物理性质（硬度、拉伸强度、伸长率等）预期涂层的厚度容易通过接枝硅氧烷组分的浓度来控制。反应性硅烷的存在特别适合于腐蚀保护，因为它充当水分清除剂以及改善与金属表面的粘附性。预计这项工作的成功完成将在腐蚀防护技术中用生物基材料取代石油基材料。该项目更广泛的影响/商业潜力是提供来自可再生资源的永久性有机涂层，为公众提供清洁技术。这些生物基涂料用于防腐蚀应用，如气体和液体输送管道，桥梁和建筑物的建筑钢筋，工业设备等。NACE研究（2002年）的结果表明，美国每年的腐蚀直接成本估计为惊人的2760亿美元-约占国内生产总值的3.1%。该项目第一和第二阶段的成功实施将产生以下技术、商业、环境和经济影响：改进腐蚀防护和易于应用，低资本投资，减少VOC/HAP和碳足迹，保护化石燃料资源，减少行业腐蚀相关成本，并为该新开发产品的销售、制造和技术支持创造多达5个额外的工作岗位。
