Learn about adhesive testing and the material testing solutions we provide within adhesive testing.
Peel adhesion is not a perfect correlation to the strength of the adhesive bond. Why? Because the test measures the initial bond, and many tapes have adhesives that build bond strength over time. Also, the test utilizes stainless steel as the surface for which the tape is applied. Typically, tape is
ASTM D5179 Standard Test Method for Measuring Adhesion of Organic Coatings to Plastic Substrates by Direct Tensile Testing. ASTM C633 Standard Test Method for Adhesion or Cohesion Strength of Thermal Spray Coatings. ASTM C1583 Standard Test Method for Tensile Strength of Concrete Surfaces and the Bond Strength or Tensile Strength of Concrete ...
Testing Solutions for the Adhesive Industry. ADMET’s reliable and easy to use materials testing systems are employed by the adhesive industry to test the peel strength, bonding, and shear properties of adhesives.
The relative strength of Araldite Standard and Loctite Hysol were compared. These adhesives are both commonly supplied in adhesion test kits but to highlight the point about availability, the Loctite was sourced in the USA as it is unavailable under that name in the UK. 10 dollies were stuck down
ASTM D3330 includes six different methods for testing the peel adhesion strength of pressure sensitive tape. The information below should help you understand the basic test procedures and the equipment required to meet this standard with accuracy.
3.2 This test method is useful for comparing adhesion or cohesion strengths of coatings of similar types of thermal spray materials. The test should not be considered to provide an intrinsic value for direct use in making calculations, such as to determine if a coating will withstand specific environmental stresses.
This is a highly subjective test and its value depends upon the inspector’s experience. A coating which has a high degree of cohesive strength may appear to have worse adhesion than one which is brittle and hence fractures easily when probed. There is no known correlation to other adhesion test methods (pull-off, tape, etc.).
ASTM adhesives standards are used internationally to evaluate adhesive performance-adhesion, strength, viscosity, fracture and other properties-- with industrial and construction materials such as wood, plastics, and metals.
