Product Description

ZERUST® AxxaVis™ HST-10 powder additive deactivates ionic contaminants found in municipal water sources that cause rust and hard water deposits on metals. AxxaVis™ HST-10 is a highly effective way to protect the interior surfaces of pressure vessels from corrosion that can rapidly form during and after hydrostatic testing. Designed for use on ferrous metals. Not compatible with aluminum. Test before use on copper, brass, or zinc.

AxxaVis™ HST-10 is designed to be safe, convenient to use, and environmentally friendly.* Used product can be analyzed for quality and, in some cases, reused. However, spent ZERUST® AxxaVis™ HST-10 working fluid may be discharged into the soil or marine environments (subject to normal legislative restrictions).
