Premium long-life radiator anti-freeze, purple
Properties
Astron Antifreeze A 040 is a premium radiator corrosion inhibitor and anti-freeze agent based on ethylene glycol, with highly effective inhibitors combining OAT and silicate technology as well as high-performance additives (Si-OAT-coolant). It ensures maximum long-term protection of all metal components in the motor. The product does not have any negative effect on coolant hoses or cylinder head gaskets.
Astron Antifreeze A 040 is nitrite-, amine-, phosphate- and borate free.
Use instructions
Astron Antifreeze A 040 – mixed with the correct amount of water – can be used without restrictions as a thermal transfer fluid in internal combustion engines made in cast iron, aluminium or a combination of these metals, and radiator systems made in aluminium or copper alloys.
Astron Antifreeze A 040 is particularly recommended for high-tech engines that require special high-temperature protection for aluminium components.
We recommend maintaining a concentration of 50% (v/v) during all seasons. Astron Antifreeze A 040 can be mixed with most coolants based on ethylene glycol. Caution: Observe manufacturer instructions. Minimum concentration: 33 % (v/v).
