Calvary Industries’ Advantech is a water-based pretreatment for metal that operates at ambient temperature and is said to be safe for mild steel washers. The solution is applied after a cleaning step and rinses in a multi-stage washer, and then dries on the part in a dry-off oven. It can also be rinsed with DI Halo in e-coat applications without reducing performance, the company says.
Advantech is formulated to improve the impact resistance and flexibility of topcoats over traditional pretreatments. According to Calvary, it has matched the performance of competitive chrome-sealed iron phosphate and zinc phosphate in SAE-J2334 cyclic testing and ASTM B-117 salt spray testing.
