Moisture and heat resistance test for adhesive

Evaluation of adhesive strength in high temperature and high humidity environments! Chemical analysis (FT-IR, GCMS, etc.) is also available to elucidate the degradation mechanisms of materials.

We conducted a "moisture and heat resistance test for adhesives" to investigate changes in adhesive strength due to the effects of moisture and heat. The test specimens were placed in a constant temperature and humidity testing machine, and after 500 hours, they were removed to measure the tensile shear adhesive strength. It is presumed that the adhesive strength decreased due to the swelling of the adhesive in a high-temperature and high-humidity environment. We can conduct various environmental tests and strength tests for various materials, not limited to adhesives. Additionally, we also provide chemical analysis to elucidate degradation mechanisms. [Test Results] - The adhesive strength (breaking stress) of the samples placed in a humid heat environment for 500 hours significantly decreased. - From the stress-strain curves of the tensile tests, a decrease in the modulus of elasticity was confirmed for both adhesives A and B. - It is presumed that the adhesive strength decreased due to the swelling of the adhesive in a high-temperature and high-humidity environment. *For more details, please download the PDF or feel free to contact us.
