CORROSION-INHIBITED ANTIFREEZE FORMULATION

摘要

CORROSION-INHIBITED ANTIFREEZE FORMULATION (D#71,000-TF-151-F) A corrosion-inhibited antifreeze concentrate formulation containing no phosphate, amine, or nitrite compounds consists essentially of: (a) a major amount of a water soluble liquid alcohol freezing point depressant; (b) from 0.1-5.0 weight percent of a C6-C12 aliphatic mono basic acid or the alkali metal salt thereof; (c) from 0.1-5.0 weight percent of an alkali metal borate compound; and (d) from 0.1-0.5 weight percent of a hydrocarbyl triazole. The concentrate formulation and aqueous antifreeze formulations of the instant invention give synergistic corrosion protection for a variety of metal surfaces as compared with compositions containing only the aliphatic monobasic acid/salt or alkali metal borate component alone.
