Designed for Acid & Base Chemical Applications


Indicote® Leak Indication Paint is a golden yellow 100% acrylic paint that instantaneously changes color through contact with liquids or vapors for immediate visual indication of leaks that are often too small to trigger an indication with conventional detection devices.

Indicote® has an operating temperature of 35 °F to 220 °F. Indicote® changes to red when exposed to acids lower than pH 4 and changes to blue when exposed to bases higher than pH8.
