Silicone glue in the process of curing with water molecules is from the surface to the inside gradually, but into autumn and winter, the temperature and humidity of the environment has a significant impact on the curing speed, the antisticking of sealant, surface dry and deep curing will be slowed down. In addition, the sealant products on the market are divided into summer formula and winter formula, different formula, curing time is significantly different, in the purchase process according to their own construction environment requirements pay attention to the distinction.
Under standard conditions (temperature (23±2)℃, relative humidity (50±5)%), the surface dry time of one-component silicone sealant in 3 hours, disadhesive time in 24 hours. Under low temperature conditions in winter, the surface drying time and antisticking time will be more obvious.
