Webinar: Performance Additives for Lubricating Greases

Wednesday, May 07, 2014

12:00 PM - 01:30 PM


Join us as Gareth Fish provides details on additives used in grease formulation.

Performance Additives for Lubricating Greases

Instructor: Gareth Fish, Technical Fellow & Strategic Technology Manager Industrial Additives, The Lubrizol Corporation

Where: STLE University, live webinar event broadcast to your computer

When: Wednesday, May 7, 2014 at 12-1:00 p.m., with optional Q&A from 1-1:30 p.m. Central Time

Cost: $39 for members, $59 for non-members

Abstract

The NLGI definition for a lubricating grease is as follows: "A solid to semi-solid product of dispersion of a thickening agent in a liquid lubricant. Additives imparting special properties may be included." The properties of the grease are generated through the combination of the base oil and thickener along with the manufacturing process, but for the majority of applications, these need to be modified with performance additives.

Additives for lubricating grease are split into two classes: physical and chemical. Physical additives are chemically inert and undergo no chemical reaction. They affect the physical properties of the grease: structure and rheology; oil bleeding; and water tolerance. Chemical additives, as the name suggests, are chemically active. There are additives that react at the surface of the lubricated contact such as corrosion inhibitors, antiwear and extreme pressure (EP) additives and those that react within the matrix of the grease such as antioxidants and dropping point enhancers.

Many additives used in grease are similar to those used in liquid lubricants, but many are unique to grease. The treat rates used in grease are also much higher than used in typical industrial lubricants. All these types of additives will be covered along with typical treat rates used in grease.

This presentation is intended for:
• Newer grease chemists with little to no experience with grease additives
• Seasoned grease chemists who want a bigger picture of where additive chemistries are headed
• Seasoned non-grease chemists who are looking to enter the grease field and want some general knowledge about grease additive chemistries and how to choose and formulate with them

Presenter Biography -

Dr. Gareth Fish obtained his B.Sc. (Honours) in Chemistry 1984 from Imperial College of Science, Technology and Medicine, University of London and a Ph.D. in Tribology 1990 also from Imperial College, under the supervision of Professor Hugh Spikes. In 1988, he joined the UK Ministry of Defence, Fuels and Lubricants Branch, at the Royal Arsenal Woolwich, in the Mechanical Testing of Lubricants Laboratory. In September 1990, he was appointed Senior, then Principal Tribologist at GKN Technology Ltd, Wolverhampton, England. In 1999 he became Global Technical Coordinator for Tribology and Grease. In 2002 he relocated to GKN Automotive, Inc, Auburn Hills, Michigan. In June 2007, he joined The Lubrizol Corporation, Wickliffe, Ohio, as Technology Manager for Grease. In 2010 he was promoted to Technical Fellow and is now the Strategic Technology Manager for Industrial Additives. He is a Chartered Scientist (CSci) and Chartered Chemist (CChem), a member of the Royal Society of Chemistry (MRSC), and the Society of Tribologists and Lubrication Engineers (STLE) and the Energy Institute (MEI). He is chair of ASTM D02 B04 Automotive Greases and D02 G07 Grease Research Techniques. He is both an STLE Certified Lubrication Specialist (CLS) and an NLGI Certified Lubricating Grease Specialist (CLGS). He has authored 35 technical papers on tribology and grease, and holds three patents. In 2000 received the Chevron Products Award of the NLGI for the 1999 technical paper “Constant Velocity Joint Greases”, in 2002 received the NLGI Fellows Award, and in 2010 & 2012 receieved the Clarence E. Earle Memorial Award from the NLGI for, in 2011 the NGL authors award and in 2013 the SOPUS prize for teaching excellence at the NLGI annual meeting.
