GB/T 22083 - 2008 focuses on architectural sealants. It systematically classifies architectural sealants, and divides different grades according to key performance such as displacement capacity. The specific requirements of each grade of sealant in terms of tensile modulus, extrusion, surface drying time, etc. At the same time, detailed test methods are given to detect whether the performance of sealants is up to standard. The standard provides a basis for the production, selection and mass supervision of architectural sealants, helping construction projects to accurately select suitable sealants, ensure the waterproof and sealing effects of building joints, and ensure the durability and functionality of buildings.
