CrestoGuard™ 400 is an aqueous solution of hydroxyphosphonoacetic acid (HPA) and is the industry’s most powerful mild steel organic corrosion inhibitor for all-organic cooling water formulations.

Provides our user with the following benefits:

  1. Better environmental profile in comparison to other available programs; approximately 93% biodegradability. 
  2. Positive payback through reduced iron fouling; improved plant integrity and maintenance. 
  3. Best available corrosion inhibitor for use in all-organic formulations, assigned to significant better performance in comparison to commodity phosphonates like hydroxyethylidene diphosphonic acid (HEDP).
