This course is written specifically for the purpose of providing a basic understanding of adhesive systems. It is a very broad subject so we are limiting the descriptive information to adhesives only and omitting sealants, thread locking adhesives, potting compounds, encapsulating compounds, gasketing materials, etc. These subjects are very interesting but complex to the point of deserving a more detailed look on an individual basis. We will concentrate solely on adhesives products used for bonding two or more substrates together. When we say systems, we are referring to 1.) Adhesives types and selection, 2.) Cleaning and pretreatment of substrates and 3.) Joint design. All three areas are integral to successful bonding, and accomplished properly, can provide for prolonged operational life. We also cover adhesive history, global markets, adhesive uses, standards and testing methods and equipment. By the end of the course, we want to impart a fundamental understanding of an industry that has significant annual growth and represents an important technology. We hope to pique your interest to the point of wanting to know more and providing a solid foundation upon which to build.

The learning objectives of this course are as follows:
This five (5) hour course is intended for those individuals who require a basic knowledge of adhesives and adhesive systems. Although it is primarily intended for engineers, engineering managers and architects, the text is written in a fashion that is easily understandable for anyone with a desire to gain knowledge over and above the “folklore” that seems to exist concerning “glues”. The only “technical” part of the course is the discussion on the Theory of Adhesion. We touch briefly on the chemistry of polymers and monomers and how they interact with substrates to form the bonds necessary for adhesion. Failure mechanics of adhesive systems are quite complicated but I have chosen a more fundamental approach that lets the reader glean a quick understanding of how to choose the best adhesive for any one given job. The text involving the adhesive selection is very informative and forms the focal point of the course. The “dos” and “don’ts are enumerated relative to surface preparation and joint design so that a starting point may be had prior to choosing the proper adhesive system. This course does not require the calculation of “wetting angles” or stresses relating to performance. The sole purpose is informative. There is a quiz at the end of the course which, is a learning tool also.
Benefit to Attendees
The purpose of this course is to provide an introductory body of information that will allow the engineer, engineering manager or corporate manager the basic resources to investigate the possibility of substituting an adhesive for an existing or envisioned mechanical fastening technique. We wish to illustrate those key design practices; i.e. adhesive selection, joint design, cleanliness, pretreatment of substrates, etc. that ensure high levels of success with any application. This course will also provide references for further study so that the understanding of basic concepts, as applied to commercial and consumer products, may be augmented for any one classification of adhesive or application. Successfully completing this course will not make you an expert or a specialist but certainly will provide you with an understanding of the basics so further study will be possible and much less confusing. Glossaries for adhesive materials and pressure-sensitive products are very complete and provide descriptive information that will definitely lessen time necessary to understand the given text. We also have provided information, relative to viable manufacturers of material and equipment, so that searching for vendors becomes less time consuming and reduces the frustration factor
The dictionary defines an adhesive as "a substance capable of holding materials together by surface attachment." This is a simple definition for materials that serve as the basis for a multi-billion dollar industry with more than 750 companies contributing to the manufacturing and sales effort. It is estimated that 50 of those companies are responsible for at least 50% of the sales dollars in the adhesive industry.
This course will examine adhesives and give an overview relative to adhesive types, uses, advantages and disadvantages, characteristics and various failure modes that could result due to use or over use. Adhesive technology is a dynamic industry with new compounds being developed frequently to satisfy growing consumer and industrial needs. “The need for speed” and bond strength, with minimal surface preparation, are the driving forces behind development efforts. Oddly enough, retail cost seems to be a lesser concern when searching for a suitable material. Get the job done right is the clarion call. Our hope is that the material contained in this document will provide the foundation and desire for further study and the student will continue learning about this dynamic technology.

This five (5) hour course is presented to those individuals who wish to know more about the subject of adhesives. We will cover the following major topics in the text:
The course is definitely written with practicality in mind so that an individual may select the correct adhesive for given substrates in question; i.e. wood, metal, paper, plastic, etc. Two of the most important sections in the text are joint design and substrate preparation. “Gluing” two substrates together is more complicated than picking the adhesive from the corner drug store, especially if the application is industrial or commercial. Cleanliness and pre-treatment are critical. We explain how to accomplish a suitable interface so maximum success may be accomplished. Since a picture is worth a thousand words, we have used many figures and tables to show and demonstrate concepts given in the text. We have done this with the hope that the reader will come away with a very good “grounding” of and appreciation for the great variety of adhesives and processes available today.
