This case study documents coating application for a 60-meter iron communication tower in coastal Vietnam. Surface prep: Sa 2½ blast, 75μm profile. System: water-based epoxy primer 80μm + water-based polyurethane topcoat 60μm. Application: airless spray, 2 coats each, 4-hour recoat interval. Result: excellent adhesion (cross-cut 0), 1000h+ salt spray, 24-month field inspection shows no defects.
