Concentrate, down to -37 °C, suitable for aluminum engines, blue, boiling point 160 °C Nitrite-, silicate-, amine-, borate-, 2-ethylhexanoic acid- and phosphate-free OAT-based ethylene glycol (MEG) radiator protection with an additive package based on OAT technology. It prevents frost and corrosion damage in the cooling water circuits of internal combustion engines, as well as cavitation on pump segments, and is particularly low-foaming. Inorganic and organic inhibitors are responsible for corrosion protection in the cooling system. It meets industry standards such as British Standard BS 6580, French Standard NF R 15-601, and ASTM D 3306. Note: When changing, please drain and flush cooling systems and expansion tanks. Do not exceed the change intervals for radiator protection specified by the respective manufacturers. The concentration should never be less than 33% and never more than 60%! Mixing table: Frost protection down to approx. - Mixing ratio Concentrate : Water -37 °C - 1 : 1 -27 °C - 1 : 1.5 -18 °C - 1 : 2 Instructions for use: Never use radiator protection concentrate neat, always mix with water. Pay attention to the correct mixing water (clean) and the correct mixing ratio according to the manufacturer's specifications (if in doubt, switch to ready-mix). Generally miscible with most radiator protection products based on 1,2-ethanol (MEG), instructions from aggregate manufacturers must be observed. For optimal corrosion protection and optimal inhibitor action, an unmixed product should always be used.
