01 / Product brief
Maximum Corrosion Protection for Outdoor Storage
High-temperature, heavy-coat zinc phosphating producing 15–25 g/m² at 65–75°C. Elevated temperature and extended reaction produce a dense, thick coating for maximum standalone corrosion protection. Salt spray exceeds 500 hours on coated and passivated ferrous substrates in independent testing.
15–25 g/m² coating weight extends salt-spray performance to 480–600 hours (with passivation) on ferrous substrates — the highest corrosion performance available from a phosphating process. Preferred where no paint topcoat is applied.
