Multigard Ethylene Glycol

Performance Specifications

This is a heat transfer fluid with an organic acid based formulation which contains no nitrites, amines, borates, or phosphates. It will provide a pH of 8.0 - 8.5 in 50% heat transfer fluid. It is designed for multi-metal systems made entirely or partly of aluminum which protect all commonly used metals that are compatable with most plastic and elastomers. Our Multigard EG 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 suppliment "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.
