Silicone weathering sealant is used in curtain wall plate joint seal silicone sealant between known and used for doors and Windows and other highways, airports, highways, Bridges and other sealing silicone sealant on the performance and functionality and weather resistance of a silicone sealant, basic can consult weather resistance performance of the adhesive, glue line with the actual structure to use.

Among the main technical indicators of silicone weatherproof sealant, the performance of construction is characterized by drooping, extrudability, surface dry time, and the performance of weatherproof sealant is characterized by displacement capacity and mass loss rate after curing. The mass loss rate of weather-resistant adhesive is equivalent to the thermal weight loss of structural adhesive. The performance change of weather-resistant adhesive after long-term use is mainly investigated. The higher the mass loss rate, the more serious the performance decline after long-term use.
