ASTM D4498-07 (2015) standard test method is used to determine the thermal failure temperature of hot-melt adhesives under static shear force. This temperature sets the maximum temperature that Adhesive must not be exposed to in actual use to avoid failure due to shear loads. The test helps users understand the thermal stability and applicable Temperature range of hot-melt adhesives by evaluating the delamination temperature under shear force, thus guiding their use and application in high temperature environments. This method provides key data to ensure the Reliability of hot-melt adhesives in practical applications.
