Super-longlife radiator antifreeze, violet

ASTRON Antifreeze A 13 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. 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 13 – 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 13 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 13 can be mixed with most coolants based on ethylene glycol.
