ADHESIVES, GLUES AND SEALANTS


Destructive testing of adhesives and bonded joints.

What are destructive testing?

destructive testing are defined as those tests that are made to a material through the use of tools or machines, which produce an irreversible alteration of their chemical composition or dimensional geometry.

destructive testing are performed on adhesive or adhesive joints that have 4 main objectives:

Due that the adhesive process is consider a special process, it is advisable or necessary, depending on the requirements of the bonded joint, a series of specimens at the same time it makes application of the adhesive, in order to check the environmental conditions, surface preparation and product set of the adhesive system (primers, activators and adhesives or glues). The number and frequency of performance of these destructive testings are determined by the degree of safety or dangers of the adhesive bonding.

adhesive properties - destructive testing

During the definition and implementation of the specimens to be used in destructive testing, it must be taken into account the following points:

Once the specimen has been made, it is then the destructive testing which verifies the following main parameters:

There are numerous standards which regulates and details the conditions, tools and steps to follow for destructive testing of adhesives and adhesive joints, the purpose of these standards is to compare and validate any adhesive or bonding anywhere in the world.
