Glass curtain wall has the advantages of strong integrity, light structure, good elastic connection, good seismic performance, convenient construction and convenient maintenance. The materials used are mainly aluminum alloy profiles and sealants two parts. Sealant selection and use of which is directly related to the structural assembly of the glass curtain wall, building leakage and other safety issues. Sealants mainly include structural sealant and weather sealant sealant. First, the choice of sealant should pay attention to the problem 1, the quality of structural adhesive requirements (1) a lot of indicators of structural adhesive, usually considered essential performance of 4,
