ADHESIVES, GLUES AND SEALANTS


Nondestructive testing of adhesives and bonded joints.

What is nondestructive testing?

Nondestructive testing are defined as those tests based on physical phenomena, whose objective is to obtain information on defects or on state of a material without causing any chemical, dimensional, or mechanical damages in the material itself.

Non-destructive tests carried out in an adhesive bonding set their objective in:

The main advantage of nondestructive test is the ability to see and localize certain defects that can occur in a real adhesive bonding, but currently they cannot describe the behavior of the zone of adhesion between the substrate and the adhesive, and also cannot obtain the mechanical characteristics of the adhesive in the joint.

Among the defects that can be identified by the use of nondestructive testing, we can cite:
