GB/T 13477.9-2017 《Test method for building sealants—Part 9：Determination of adhesion/cohesion properties after immersion in water》 Related products

GB/T 13477.9-2017 Specifies the determination of tensile adhesion of building sealing materials after immersion in water. It details the test process, covering the preparation of the specimen, the sealing material is bonded to a specific substrate; the immersion conditions are specified to simulate the humid environment. After immersion, the specimen is stretched, the bonding state of the sealing material and the substrate is observed, and the bonding strength is measured. The standard evaluates the bonding performance of sealing materials under humid and tensile conditions through quantitative testing, providing a key mass detection basis for the application of building sealing materials in humid areas, ensuring the Reliability and durability of sealing projects in complex environments.
