Anticorrosion antifreeze "B - 72" is "BIO" low-freezing coolant concentrate, produced on the basis of 1,2,3-propanetriol, higher alcohols and inhibitors.
Created with care for the environment and living organisms, it is 100% biodegradable. Its formulation is "green" and less toxic than that of MEG-based antifreezes. Uses ferrous and non-ferrous metal inhibitors, including borates and silicates.
It is used for year-round cooling of internal combustion engines. It is used as a heat carrier for air conditioning, geothermal and solar installations, in heating and cooling systems.
"B - 72" is produced on the basis of 1,2,3-propanetriol <80%, MEG <10%, carbinol <5%, disodium tetraborate anhydrate <3%, anticorrosive and antiwear additives.
