Antifreeze cooling liquid with high heat carrying capacity
An antifreeze cooling liquid with a high heat carrying capacity is composed of: at least 33% of monopropylene glycol; at least 2% of a triazole, not more than 1% of biocides, the addition of water to make 100%.
1. An antifreeze cooling liquid with high heat carrying capacity usable in environments in which there is gold or silver, the liquid consisting of:
about 40% of monopropylene glycol,
about 5% of a triazole,
not more than about 1% of biocides,
the addition of water to make 100%.
2. The liquid according to claim 1 , wherein the triazole is a benzotriazole.
