Abstract:
Disclosed are a water-soluble metal-processing agent and a coolant both of which have excellent microbial deterioration resistance and are less likely to go rotten, a method for preparing the agent or the coolant, and a metal processing method. The water-soluble metal-processing agent or the coolant comprises an N,N,N′,N′-tetraalkyldiamine compound. The metal processing method is characterized by processing a metal of interest by using the water-soluble metal-processing agent or the coolant.
