Opticool Antifreeze Red 50% is pre-diluted, ready-to-use ethylene glycol based engine coolant, which uses Organic Acid Inhibitor Technology and is free from nitrites, amines, phosphates, borates and silicates. It is BTC Classification Type 4E. Fleet trials have shown that when used at the correct concentration coolants based on Organic Acid Inhibitor Technology continue to provide effective corrosion protection for up to 5 years or 250,000km for passenger cars and 500,000km in commercial vehicles.
Opticool Antifreeze Red 50% provides excellent protection to engine cooling systems, whether they are predominantly of ferrous or aluminium construction. Unlike traditional coolants which employ inorganic inhibitors, Opticool Antifreeze Red 50% has excellent hard water stability and very low inhibitor depletion rates.
