PGAL – Aluminum Safe Glycol

ig-loo PGAL organic acid-based formulation contains no nitrites, amines, borates, or phosphates and provides a pH of 8.0-8.5 in 50% heat transfer fluid. It protects all commonly used metals, including aluminum, up to at least 350°F (176°C), and it is compatible with most plastics and elastomers.

ig-loo PGAL can be used in any heating/cooling system, but it is the best choice for high-aluminum-content systems operating above 150°F (65°C). The organic acid salts used in ig-loo PGAL coat all metal surfaces for protection from corrosion. Azoles are included to supplement “soft” metal protection (copper, brass, solder, and aluminum). Organic acid depletion rates are very slow, resulting in a fluid life at least as long as phosphate-based fluids without the necessity of boosting the phosphate content periodically.

ig-loo PGAL Aluminum Safe Inhibited Propylene Glycol available in Prediluted and Full Concentrate.
