We rely on electronics for almost every aspect of our daily lives. With the advent of compact components and circuitry, it is difficult to think of many products that do not incorporate electronics in some fashion. What you might not think about is how fragile these electronics can be and how they can become easily damaged or degraded by environmental conditions.

Among all chemical curing techniques, convection and radiant thermal curing represent the most widely used applications for adhesives and sealants. During the curing process, adhesives and sealants usually pass through two physical transformations—evaporation and condensation—while being applied to other materials.
