ANTIFREEZE/COOLANT COMPOSITION |
| 摘要 |
<p>A durable antifreeze/coolant composition for coolants for the cooling systems of internal combustion engines is disclosed. The composition is excellent in inhibiting corrosion of metal portions, especially iron and aluminum portions and effectively inhibits cavitation damage. The antifreeze/coolant composition includes about 0.1-8.0% by weight of C6-C12 aliphatic dibasic acid and/or an alkali metal salt thereof and about 0.1-10% by weight of p-toluic acid and/or an alkali metal salt thereof.</p> |
