| 摘要： | These 3-coat moisture-cured (MC) urethane commercial products formulated for protecting new steel (SSPC-SP 10) and power tool-cleaned steel (SSPC-SP3) surfaces against corrosion were evaluated; the total coating film thickness was about 75 microns. Zinc-rich ME-urethane primers were used for SSPC-SP 10 steel surfaces whereas the primers for SSPC-SP 3 surface contained zero or a small amount of zinc; the same midcoats and topcoats were used for both steel surfaces. Sealers with film thickness of 25 microns were also studied for any potential effect on coating performance of the coating systems for power tool-cleaned surface. The volatile-organic-compound content of all the coating materials was below 340g/L. The Federal Highway Administration (FHWA)-developed cyclic testing method was conducted to compare the performance of these coating systems. The test included freeze, ultra-violet light/condensation, and salt fog/dry air cycles. An aggressive outdoor marine exposure at Sea Isle City, New Jersey, was also performed for all the coating systems for comparison. |
