Adhesives and Tape Testing
Testing, Analysis and Inspection of Adhesives and Tapes
Adhesives are finding increasing use across many industries, including construction, automotive, packaging, electronics, medicine, and many consumer goods. Shimadzu offers a wide range of instrumentation to evaluate the physical and chemical properties of adhesives, sealants, pressure sensitive adhesives, and coatings. Our universal test machines are available with a large selection of accessories such as lap shear, peel, and climbing drum jigs to measure the bond strength of adhesives and substrates. Thermal chambers are available for high-temperature testing, and our materials testing software provides flexible and intuitive test method development and data processing. Shimadzu’s complete line of analytical and thermal instruments can also be used to evaluate the chemical and thermal properties of adhesives.
Analysis of Hardening Process in Adhesive (FTIR)
When polymer materials are heated, irradiated with light, or mixed, some of the molecular structures can undergo changes that are a function of time. Infrared spectrophotometers (FTIR) provide an effective measurement method for tracking such changes, as they offer the ability to simultaneously track the changes of multiple absorption peaks. When the main components of an epoxy-based adhesive are mixed with its hardener, they react and start hardening as a function of time, according to the process shown in the figure below. The changes in functional groups were investigated by measuring the hardening process at fixed intervals.

180° Peeling Test for Adhesive Tapes [Standard No. ISO 29862:2007 (JIS Z 0237:2009)]
As the chemical industry has developed, adhesives using synthetic polymers as raw materials have been commercialized. These adhesives are often used in a variety of industrial fields, including electronics and electrical machinery. This article introduces an example of a 180° peeling test for adhesives used in adhesive tapes.

Analysis of Vinyl Acetate-Based Adhesives (GCMS)
Vinyl acetate-based adhesives were analyzed by evolved gas analysis (EGA). The resulting chromatograms are shown in Fig. 1 and the mass spectra for the main peaks are shown in Fig. 2. The primary component of peak 1 is methyl acetate, which is presumably the solvent. Peak 2 is acetate and peak 3 is difficult to identify because it is a mixture of many substances.
90° Peeling Test for Adhesive Tapes [Standard No. ISO 29862:2007 (JIS Z 0237:2009)]
As the chemical industry has developed, adhesives using synthetic polymers as raw materials have been commercialized. These adhesives are often used in a variety of industrial fields, including electronics and electrical machinery. This article introduces an example of a 90° peeling test for adhesives used in adhesive tapes.
