GB/T 13477.15-2017 is used to determine the adhesion of building sealing materials after heat, artificial Light source through Glass and water exposure. This standard precisely sets the exposure environmental conditions and standardizes the preparation and exposure process of the specimen. The sealing material specimen is placed in a coordinated environment of heat, light and water to simulate the actual working conditions of the building. After exposure, the bonding state between the sealing material and the substrate is detected, such as changes in bond strength and whether there is debonding phenomenon. This provides a basis for evaluating the bonding Reliability of long-term use in complex natural environments, and ensures the durability and sealing of building sealing projects under the influence of various factors.
