Effect of Surface Coating Condition on High‐friction Organic Zinc‐rich Paints for HSFB Joints

Abstract With the development of paints, high‐friction organic zinc‐rich paints with slip coefficients more than 0.45 have been advanced, making it possible to obtain sophisticated and higher quality high strength bolted friction joints. Moreover, comparing inorganic used at present, are appropriate for using in situ construction. However, since application conditions coatings not specified, is recommended that a test should be carried out separately each surface preparation confirm coefficient. In this study, tests were on joint specimens investigate influence zinc rich paint film thickness Furthermore, based experimental results, can consistently produce coefficient proposed.
