摘要: The present invention relates to a monocarboxylic acid based antifreeze coolant formulation for applications such as gasoline engines which may be used inhibition and prevention erosion corrosion of aluminum the other metals exposed an aqueous liquid in automotive systems. further inhibits mineral scale. It packaged ethylene glycol additive use new or concentrated package reinhibition coolant. combination mixture propylene glycol, monobasic carboxylic organic acid, azoles, low levels molybdates provides resistance. A heavy duty formula more suited diesel also contains nitrite salt and/or nitrate siloxane stabilized silicate, combinations thereof provide synergistic protective effect against cavitation liquids reducing rate is effective at relatively concentrations varying pH ranges.
