Adhesive Basics

Request a Demo

Adhesives are compounds that can be used alone or supplement another joining mechanism to hold two substrates together. The type of adhesive used in each application depends on the nature of the substrates and the conditions to which the adhesive joint will be exposed. This course will describe the basic theories of adhesion, adhesive classifications, and common adhesives. It will also discuss important surface preparation and adhesive application considerations, and some advantages and disadvantages of adhesives compared to other joining mechanisms.
