The course on Light-Cure Adhesives will introduce the student to a method of obtaining extremely rapid cure times for adhesive materials. These materials react to UV and visible light in a fashion that can provide a permanent “set” in less than a minute. Curing in the presents of UV light has been usable technology for quite some time but the development of materials that will cure when subjected to visible light are fairly new to the adhesive industry. These materials react differently than other adhesives material classifications. We will explore the chemical mechanism by which this is possible as well as 1.) Mechanical characteristics, 2.) Material categories, 3.) Equipment necessary to project light on the substrates, 4.) Applications, 5.) Benefits and 6.) Safety aspects of the light cure process. We also will take a quick look at those vendors selling into the marketplace and specialty materials available for difficult jobs. When completed, the student will have a working knowledge of light cure adhesives and will be able to talk intelligently with vendors and professionals in the adhesive field.

The learning objectives for this course are as follows:
This course is intended for those people eager to obtain a basic understanding of the rapidly growing field of light-cure technology. The processes are very dynamic and have made possible the assembly of devices previously very difficult to produce; i.e. syringes, respirator masks, eye glass frames, traffic lights, etc. Those taking this course will gain knowledge of a technology that is making possible a variety of products which would have existed in different designs a decade ago.
Benefit to Attendees
Attendees will gain a working knowledge relative to the materials available, typical applications and the manufacturing processes used for the assembly of products. The process of light curing is fascinating and involves the use of very special equipment not entirely common to standard assembly techniques. We will also discuss, in depth, the safety aspects and handling of materials used in this fast moving industry.
Light-cure adhesive technology offers a new approach to bonding substrates, by using either UV light or visible light. Depth of cure, extremely rapid cure time and very easy dispensing of material are all direct benefits when using these materials and associated methods of application. This all equates to lower costs of assembly, added freedoms when designing products and components and the saving of valuable production time. This method of adhesion is extremely valuable when bonding thin films, needing fewer safety risks to eyes and skin and bonding heat sensitive materials. Also, this process can lessen or eliminate the need for costly and harmful chemicals from the workplace. In addition, the use of light cure adhesives can result in a very clean and “friendly” worker environment with no significant material disposal costs.
