Jimmy Yinjun Zou, Ph.D. – Shifting Perspectives: Formulating for the Performance and Longevity of Metalworking Fluids


The complexity of metalworking fluids (MWFs) has significantly increased in recent years with new technologies and overall growing environmental, health and safety (EHS) concerns. With a decreasing chemical portfolio resulting from compliance challenges and an increasing cost-performance requirement from end-users, MWF formulators face more challenging market demands.

As MWF formulators search for innovative technologies to meet the ever-changing landscape, the new formulation development has a ripple effect on the labeling, cost and end-user preferences that must be addressed. In many cases, the bigger the formulary change, the more significant the ripple effect. To help formulators address the challenges, this presentation focuses on a new perspective for scaling changes in working formulations while managing the ripple effect. In the formulations demonstrated, fluid life, pH stability and multi-metal compatibility become easier to achieve with optimised additive use.


Yinjun Zou (Jimmy) is a Customer Application Specialist at ANGUS Chemical Company, headquartered in Buffalo Grove, Illinois, U.S.A. He is based in the Singapore Customer Application Center, leading the technology and application development in metalworking fluids, electronic chemicals, water treatment, and gas treating for markets in Japan, Korea, Southeast Asia, Australia, and New Zealand.

He received his Ph.D. in Organic Chemistry from Nanyang Technological University (NTU) in 2014 and a degree of Applied Chemistry from Wuhan University. He worked as a postdoctoral research fellow in nanomaterials at NTU before joining ANGUS.
