AC PROTECT 101 – Anticorrosion additive for hydraulic pressure testing
Concentrated non-foaming additive for metal protection during hydraulic testing. Effective in saline, acidic or alkaline aqueous environments. Nitrite-free, VOC-free, compatible with hard water and indirect food contact.
Description
AC PROTECT 101 is a concentrated liquid solution formulated to provide optimal corrosion protection during hydraulic pressure tests, immersion tests or pressure testing of tanks, vessels, cylinders or circuits. Versatile, it is effective on ferrous, light and copper-based metals, even in slightly saline, acidic, neutral or highly alkaline aqueous environments. Its nitrite-free, boron-free, molybdate-free and silicate-free formula is non-foaming, VOC-free and compatible with hard water. It is also approved for indirect food contact, making it safe to use in regulated environments.
