3.3 polyurethane coatings in corrosion
Polyurethane coatings with good weather, good gloss, color stability, corrosion resistance, acid rain, low temperature construction, good coating can be coated cover performance, easy to repair, coating with good flexibility and good ductility, impact resistance and anti-shock effect of good performance benefits, its outstanding overall performance in corrosion engineering to be widely used. Compared with other coating, polyurethane coating system the lowest life cycle cost, and can reach Europe and the United States on the high demand of volatile organic compounds emissions standards. Its excellent chemical properties, good economic efficiency and low VOC standards to win more and more professional and user acceptance, polyurethane has been successfully applied to the bridge, offshore platform, port machinery, plant equipment, pipelines and storage tanks airports, sports venues and other construction facilities. Worldwide, with the coating on the project and the apparent protection requirements continue to increase, polyurethane in the field of application of steel corrosion are also constantly evolving. In addition to conventional two-component polyurethane technology, single-component moisture curing polyurethane and polyurea aspartic acid ester has also expanded polyurethane anti-corrosion coatings in the field of application of space, and many engineering applications in Europe and the United States on a number of engineering problems provided solution. Moisture curing polyurethane and aspartic acid ester polyurea coating also has the follow-spaced fast curing characteristics of the two products together in the same system used to fast feature superimposed to form a coating system, fast processing. On the other hand, moisture-curing polyurethane and polyurea aspartic acid ester also has excellent corrosion resistance, both supporting the use of further strengthening the system of high performance, heavy-duty engineering advantages. Therefore, one component moisture curing polyurethane and polyurea aspartic acid esters as anti-corrosion application of new technology in China and further development is inevitable and it will be successful.
