Scope

Main technical content: High-performance silicone structural sealant for building curtain walls is a type of silicone structural sealant used for the assembly of glass curtain walls. Under standard conditions, its tensile strength standard value is not less than 0.85MPa, and the strength retention rate after aging under various conditions is not less than 75%. The silicone structural sealant products of this group standard not only meet the 6-fold safety factor required by the European standard ETAG 002-2012, but also satisfy the requirements of the mandatory standard JGJ 102-2003 "Technical Specifications for Glass Curtain Wall Projects" regarding the design value of the structural sealant's strength. It has a longer service life and improves the safety performance of the curtain wall. This group standard comprehensively enhances the tensile adhesion and shear performance of the structural sealant, adds the detection item of alkane plasticizers, and sets stricter requirements for thermal stability. It completely prohibits the addition of alkane plasticizers such as white oil and liquid paraffin, eliminating the safety hazard of "oily sealant", and the standard overall meets international levels.
