Radiator antifreeze, purple
Properties
Astron Antifreeze A 12+ is a radiator corrosion inhibitor and anti-freeze agent based on ethylene glycol. It is free of any potentially hazardous substances such as nitrites, amines and phosphates. Thanks to the optimised combination of highly stable inhibitors based on silicate-free carboxylic acid technology, Astron Antifreeze A 12+ offers excellent protection against corrosion and cavitation and prolongs the coolant change interval. Other additives prevent deposits and foaming of the coolant. Astron Antifreeze A 12
offers year-round protection against frost and corrosion during the entire service life of the engine. The product does not have any negative effect on coolant hoses or cylinder head gaskets.
Use instructions
Astron Antifreeze A 12+, mixed with the correct amount of water, can be used without any restrictions as a thermal transfer fluid in internal combustion engines made in cast iron, aluminium or a combination of these two metals, and radiator systems made in aluminium or copper alloys.
Astron Antifreeze A 12+ is particularly recommended for light-alloy engines where the aluminium must be protected against the effect of increased temperatures. We recommend maintaining a concentration of 50% (v/v) during all seasons.
Astron Antifreeze A 12+ can be mixed with most coolants based on ethylene glycol.
