ASTM D4499-07 (2015) Standard Test Method is used to evaluate the thermal stability of hot-melt adhesives under high temperature conditions. This method evaluates the thermal stability of hot-melt adhesives by monitoring their performance changes in the molten state, including viscosity, Color, epidermis formation, and phase separation. hot-melt adhesives may undergo changes during processing, such as viscosity changes, phase separation, or Color changes, which may affect the application mass of the Adhesive and the operation of the device. This test method provides comparable data suitable for evaluating the Stability of different gluing agent formulations, assisting in the selection of Spreader equipment and the development of treatment conditions. However, this method has different applicability to different types of hot-melt adhesives, and the specific accuracy and scope of application will be detailed in the standard.
