20 minutes with Michael Stapels : This research chemist with Kao Chemicals GmbH discusses foam countermeasures and why he recommends ethercarboxylic acids for the formulation of metalworking fluids.

Ethercarboxylic acids (EC) for the formulation of metalworking fluids; benefits and advantatges. Using ehtercaboxylic acids in the emulsifier package decreases the fluids sensitivity toward water quality and as the main use is as co-emulsifiers at low dosage, an optimized cost/performance fluid can be developed. Furthermore foam can be controled with the latests propoxylated EC launch to the market.
