Dober Chemical Corp. D17-A

Dober Chemical Corp. D17-A is a single component additive system used to blend light-duty, extended life coolants meeting ASTM D3306 standards. This additive package contains extended life corrosion inhibitors based on organic acids and provides maximum protection against damaging rust and corrosion in engine cooling systems. This inhibitor package is free of nitrite, amine, phosphate, silicate, and borate. This patent pending technology does not use 2EH acid nor any other organic acid that is aggressive to hoses and gaskets. Coolants made from D17-A are suitable for use in late model passenger cars and light-duty trucks.
