ON GUARD™ Acid Detecting Paint is a durable, industrial coating with a unique acid-sensitive component, which changes color (golden yellow to brilliant red) when exposed to acid or acid vapors pH 3 or lower. ON GUARD™ provides an immediate visual indication of a spill or leak, often at quantities that are too small to trigger an exposure with conventional detection devices. This is a lead-free, all-organic, acrylic modified, alkyd enamel. Use on potentially hazardous surfaces such as valves, pipes, pumps, flanges, tanks, sample ports, flow indicators, expansion joints, weld sites, clamps, hose connections, truck tanker or tanker car domes, threaded connections, or any place where an accidental leak or spill may occur. The reaction of ON GUARD™ to acids pH 3 or lower is instantaneous.

TYPICAL USE: Use ON GUARD™ over primer as a top coat. The use of ON GUARD™ White Primer #315 is strongly recommended. This product may cause lifting of inferior sub coats. Surfaces must be clean, dry, rust, dust, oil, and contamination free. ON GUARD™ may be used over existing paint if the user is assured that the sub coating is stable and the surface is clean, dry, rust, dust, oil, and contamination free.

THINNING: ON GUARD™ can be reduced with Xylene solution, if desired. For air spray, thin up to 10%. For airless sprayer, brush or roller, thin up to 5%.

STORAGE TEMPERATURE: Minimum 20 °F (-7 °C)/Maximum 110 °F (43 °C).
SHELF LIFE: Two years in the factory-sealed can at the above storage temperature.
MIXING: Stir ON GUARD™ thoroughly, making sure that no pigment remains on the bottom of the can.
COVERAGE RATE: 250 to 300 square feet per gallon. Allow for overspray and surface irregularities.
APPLICATION PROCEDURE: Apply ON GUARD™ to achieve 4 mil dry thickness (2-3 brush coats).
SURFACE TEMPERATURE: Minimum 40 °F (4 °C) / Maximum 120 °F (49 °C)
CLEAN UP INSTRUCTIONS: Clean all equipment immediately after use with Xylene. Flush and clean spray equipment before material dries.
APPLICATION EQUIPMENT: Air or airless spray, brush or roller.
