Engine Coolant

It is an ethylene glycol or propylene glycol based homogeneous, liquid chemical that reduces the freezing point of the cooler, increases its boiling point and prevents rusting when added to the cooling systems of the engines.

Concentrated Antifreeze: Antifreeze produced without being diluted with water, but required to be diluted with water when in use.r.

 Diluted Antifreeze: Antifreeze released to the market, diluted in volume with water.

How to Use Antifreeze

Concentrated Antifreeze freezes at about -18 ⁰C; however, when mixed with water, the mixture starts to freeze at lower temperatures. Antifreeze not only decreases the freezing point of water mixtures but also increases their boiling point

Characteristics of Pure Water to be Used in Antifreeze Dilution
 

Types of Antifreeze

Inorganic acid technology; commercial antifreezes manufactured using mineral/inorganic inhibitors such as phosphate, borate, silicate, nitrite, and nitrate, etc.

Organic acid technology; organic antifreezes containing only organic corrosion inhibitors such as carboxylates.

HHybrid acid technology; hybrid antifreezes in which both inorganic and organic acid technologies are used.

Antifreezes with different additive technologies should not be mixed under any circumstances

Reserve Alkalinity in Antifreeze

It is a parameter used to determine the amount of alkaline components in engine coolants and is a quality control test frequently used during the production phase. Alkaline inhibitors contained in antifreeze provide a buffering effect and neutralize acids in exhaust gas leaks in the cooling system.

Colors of Antifreeze

Special pigments included in the antifreeze give it a color; however, the color or color tone is not a parameter indicator for quality.
