Adhesion is the bond stth mrengeasurement of a coating to a substrate. When an adhesive is bonded on an item or surface numerous physical, mechanical and chemical forces come into play, which any have an effect on each other. These need to be tested before a product can be used. The large number of different adhesives products, substrates and applications as well as the adhesion behaviour of products such as creams, gels, paints and varnishes require different adhesive tests.
Adhesion testing is often associated with adhesives, sealants, laminates, electronics, cosmetics, medical device packaging, general packaging seal strength and applications where bond strength measurement is critical for research and quality control applications.?/span> Stud pull coating adhesion testing for instance is a very common test used in microelectronic coatings or other forms of "thin film" application on rigid substrates.
Typical test measurements include:
§ 180 degree and 90 degree peel tests
§ Lap shear tests for evaluating the shear strength of adhesives for bonding two surfaces together and welds such as metal and plastic welds
§ Coating cohesion - adhesion or bond strength of a coating to a substrate such as paints or varnishes
§ Tackiness
§ Stringiness
§ Creep
§ Cure behaviour
§ Tensile strength
§ Seal strength, peel strength and adhesion strength tests to determine adhesion strength of flexible plastic packaging
