MULTIGARD PROPYLENE GLYCOL

Performance Specifications

This is a heat transfer fluid with an organic acid based formulation which contains no nitrites, amines, borates, or phosphates. This will provide a pH of 8.0 - 8.5 in 50% heat transfer fluids. It is designed for multi-metal systems made entirely or partly of aluminum which protects all commonly used metals that are compatable with most plastic and elastomers. Our Multigard PG can be used in any heating/cooling system but is usually recommended for high aluminum content systems operating over 65°C. Azoles are included to supplement "soft" metal protection (copper, brass, solder and aluminum). The organic salts used will coat all metal surfaces and protect it from corrosion. The water used to dilute can be low hardness, city or well water although deionized or distilled water is best.
