A Meeting of the Adhesion Society

Annually, scientists, engineers, manufacturers, and students professionally concerned with the science and technology of adhesion, gather for a meeting of the Adhesion Society. Since 1978, this gathering has brought together these great minds to discuss, present, and learn the results of research and the newest findings in the science of adhesion.

BTG Labs’ Chief Scientist Dr. Giles Dillingham has been presenting regularly since the late 1980s. In 2006, he was elected Fellow of the Adhesion Society in recognition of his contributions.

This year he will be presenting at the 40th Annual Meeting happening February 26 – March 1 in St. Petersburg, Florida. Dr. Dillingham will present on a paper entitled, “Control of Cleaning Processes to Maximize Sealant Performance.”

Controlling the cleaning processes of sealing surfaces in power train components is the key to long life and low warranty percentages in automotive manufacture. One of the final steps in the die-cast and machining process is cleaning. Current commercial washer systems can be quite effective at removal of particulate contaminates. The efficiency of washer systems has traditionally been evaluated using the Millipore Test. This method measures the mass of particulates post washing.

Achieving Adhesion in Automobile Manufacturing

As RTV sealant, used to create FIPG (formed-in-place gaskets), is becoming more prominent in the automotive industry, ensuring the adhesive success of this sealant is key to a successful automobile. These seals rely on establishing and controlling surface cleanliness on a chemical level, not a particulate level. This new technology is forcing manufacturers to reevaluate the performance of parts washers.

This paper details and exemplifies how surface energy is directly proportional to chemical cleanliness. BTG Labs’ Surface Analyst™ provides contact angle measurements that provide a rapid quantification of washer performance to determine surface energy and therefore, the cleanliness of the machined component post-wash. This surface energy value correlates very well to successful FIPG adhesion.

In addition to this presentation, Dr. Dillingham will also be presenting two different short courses during the Annual Meeting entitled, “Surface Energetics and Adhesion” and “Surface Modification and Surface Analysis.”
