Product Description
DOWFROST™ LC Inhibited Propylene Glycol-Based Heat Transfer Fluid
DOWFROST™ LC Coolants are dyed a fluorescent yellow-green color. The addition of this dye helps to identify the location of a possible leak within a system. Coolant in the system should remain relatively clear with a fluorescent yellow-greenish color and no evidence of cloudiness or suspended solids as it operates. The appearance of cloudiness or suspended solids normally indicates problems with corrosion (incompatible material) or is the result of mixing the DOWFROST™ LC with poor quality dilution water. DOWFROST™ LC Coolants which are in use for an extended length of time may not exhibit the same bright color and can appear more brown or black in color.
DOWFROST™ LC 25 and DOWFROST™ LC 55 Coolants are pre-diluted mixtures at concentrations of 25% and 55% by volume of glycol, respectively. DOWFROST™ LC 25, containing 25% propylene glycol, represents the minimum allowable concentration since concentrations below 25% will support biological oxidation of the glycol. Propylene glycol is highly bio-degradable when diluted with water below 15% by volume of glycol and will support bio-oxidative degradation at concentrations between 15% and 25% by volume of glycol.
