This short course will provide an excellent introduction to the science and technology of adhesion and adhesives for those who have not had a formal course, or for anyone who might like an up-to-date refresher course by one of the leading experts in the field.  The combination of an excellent experienced teacher, a convenient location in the Bay Area, and a low price, makes this an exceptional opportunity.

Please mention to those of your colleagues and friends who are not on the GGPF mail list but who might benefit from this course.  Many people who work with adhesives have had little opportunity for classroom exposure to this special class of materials or cannot find the time away from work to take a full-semester class. This short course should be highly useful for anyone in such a situation, and we believe it represents excellent value. The fundamentals covered by the course are equally applicable across all types of applications.

Course details and registration information are given below.

Continental breakfast and lunch provided on site each day, as part of course expense (no additional charge).

Wine & Cheese reception will be provided at end of lectures on the first day only.

Detailed Course Description follows:

This course is designed to provide fundamental and applied information about adhesives and adhesion for adhesive users and adhesive formulators in any industry. The fundamental concepts presented in the course are also useful to persons who work with or use coatings. Although targeted towards engineers and scientists, marketers and procurement personnel can also gain knowledge useful to their jobs. If you are contemplating adhesive applications, need to meet certain specifications and regulations or want to resolve adhesive bonding problems, this course will provide valuable insights.

Course Objective
The objective of this course is to provide a fundamental understanding of adhesion and the chemistry of adhesives and their physical properties. The course is primarily concerned with organic-based adhesives.The emphasis will be the use of fundamental knowledge to solve practical problems. In the lectures and discussions, applications of adhesives in the electronics, automotive and aerospace industries will be emphasized. Case studies in these industries will be used to illustrate the fundamentals taught in the course.

Expected Outcome
Upon completion of the course, attendees will have gained an understanding of the phenomenon of adhesion, the chemistry and physical properties of adhesives and the rudiments of the mechanics of materials and adhesive bonds. The attendee will understand what it takes to make an adhesive bond appropriate to his or her application.
How You Will Benefit From This Course
· Learn basic polymer chemistry and physical properties as they are important to adhesive technology
· Develop an understanding of how adhesives are tested and what those tests and test results mean
· Learn the fundamentals of surface science and how they are applied in adhesion science and adhesive technology
· Learn how and why surface preparations are done to enhance bond strength and durability
· Gain an understanding of the basic chemistry of adhesives and from that be able to pick which adhesive is best for your application
· Knowing the "best practice" in adhesion science will help save money for your firm
· If something does go wrong, knowing the fundamentals will help pinpoint the problem
· Learn how adhesives have been applied in key industries such as aerospace, automotive and electronics.
