<p>Known cooling and release agents or lubricating agents are not biodegradable and tend to form undesired layer buildup when applied repeatedly to the casting die. The invention therefore proposes using a concentrate for producing a cooling and release agent for reusable casting dies, particularly steel casting dies, or a cooling and lubricating agent, particularly for machining, having an active sub¬stance dissolved in water and comprising a protein having a weight proportion of 10% to 50%. Good releasability of the cast parts from the casting die and a good cooling effect on the casting die are obtained using such a cooling and release agent or lubricating agent. Said agent is further biodegradable.</p> |
