Generally speaking, in the range of 5~40℃, normal construction can be carried out. When the surface temperature of the substrate is higher than 50℃, please stop the construction. If the construction is continued at this temperature, although the curing speed will be accelerated, at the same time, the small molecular products will not be discharged in time, resulting in the formation of bubbles. When the temperature is too low, the curing speed will slow down, shrinkage may occur, and the adhesive layer will be out of shape. Silicone sealants are not suitable for all occasions, such as places that have been soaked in water for a long time, frosted or too humid, and the surface of the substrate is not clean enough, and it is not easy to bond with oily materials.
