The integrated panel for external wall insulation and decoration has good adhesion and sealing performance. After curing, it has good adhesion and sealing performance, and is resistant to extreme weather environments such as high and low temperatures, ultraviolet rays, rain, snow, hail, etc., with excellent performance. Good adhesion, strong adhesion to the exterior wall insulation integrated board surface, excellent tensile and compressive properties, fully adapting to the high and low temperature shrinkage and expansion of the board. The cured sealant is at -40 ° C; C-120° Maintain good elasticity between C and will not harden or crack.
