The ethylene glycol coolants are designed with a polyorganic acid formulation to virtually eliminate scaling problems while providing added protection against metallic corrosion and erosion pitting – even in extreme temperatures and operating conditions – via a 50/50 premix compatible with all other coolants and all cooling system materials, including hoses, gaskets and plastics. The reformulated propylene glycol coolant offers many of the same benefits in a low-toxicity biodegradable option.
