Premium radiator anti-freeze
Properties
Astron Antifreeze A 048 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. Due to an optimal combination of inhibitors based on the carboxyl technology as well as silicates and borates (hybrid coolant).
Astron Antifreeze A 048 assures efficient and long lasting protection from corrosion for an extended coolant service life. Further additives prevent foaming of the coolant liquid, provide correct cavitation protection and prevent deposits.
Astron Antifreeze A 048 offers a year round, maintenance-free anti-freeze and over-heating protection due to an higher boiling point. The product does not have any negative effect on coolant hoses or cylinder head gaskets.
Use instructions
Astron Antifreeze A 048 – 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. We recommend maintaining a concentration of 50% (v/v) during all seasons.
Caution: Observe manufacturer instructions.
