附着力测试 / 粘合力测试
Adhesion is the bond strength measurement of a coating to a substrate. When an adhesive is bonded to an item or surface numerous physical, mechanical and chemical forces come into play, which may have an affect on each other. These need to be tested before a product can be used.

Determination of the failure point can be critical for the final use of the material and the adhesive. There are a large number of different adhesives products, which require different testing methods to characterize the properties of the material. Some examples include substrates, glue, creams, gels, paints and varnishes and bonding of different materials together in layers which all require different adhesive test methods.

Determination of the failure point can be critical for the final use of the materials depending on the final product they have been designed for. Tests can also be done at different temperatures to simulate real world use for the materials. Material characteristics can change at high or low temperatures due to expansion and contraction.

Adhesion testing is often associated with adhesives, tape, 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. 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 behavior
  • Tensile strength
  • Seal strength, peel strength and adhesion strength tests to determine adhesion strength of flexible plastic packaging

Adhesion testing can be carried out on a range force and material testing systems which will depend on your application needs, force capacity, and the data you require from your test results. We have a wide variety of force gages, motorized force test stands, and material testing systems and software to meet your application needs.
