Henkel Bonderite 37 Make Up and Replenisher B Phosphate Conversion Coating

Bonderite 37 chemicals are formulated primarily for treating hot-dip galvanized and certain continuous electrogalvanized surfaces which are difficult to coat with other materials. Applied by spray or immersion, the treatment will prevent white spots, seediness and pinpoint buildup. Steel may be given an excellent coating by adding Accelerator 130 or 131, and the process is well suited for mixed production of galvanized and steel. Limited quantities of aluminum can be coated satisfactorily. If much aluminum is to be treated, other processes are preferred. Cadmium must never be run through the solution because it will poison the bath.Application: Zinc Phosphate Conversion Coating
