The first problem caused by the sudden drop of ambient temperature to good price and quality SILICONE STRUCTURAL SEALANT material is that the curing is slow in the application process. The curing process of good price and quality SILICONE STRUCTURAL SEALANT material is a chemical reaction process, and the ambient temperature and humidity have certain effects on its curing speed. For one component good price and quality SILICONE STRUCTURAL SEALANT material, the higher the temperature and humidity, the faster the curing speed will be. After winter, the temperature drops suddenly, and the curing reaction of good price and quality SILICONE STRUCTURAL SEALANT material is affected with low humidity, so the curing of good price and quality SILICONE STRUCTURAL SEALANT material is slow. Generally, when the temperature is lower than 15 ℃, the curing of good price and quality SILICONE STRUCTURAL SEALANT material becomes slower.

Solution: If the user wants to work in a low temperature environment, it is recommended to carry out a small area sealant application test and a peel adhesion test before use to confirm that good price and quality SILICONE STRUCTURAL SEALANT material can be cured, well bonded, and has no appearance problems before large-scale use. However, when the ambient temperature is lower than 4 ℃, the construction of good price and quality SILICONE STRUCTURAL SEALANT material is not recommended. If the sealant is applied in a factory where conditions permit, it can be considered to improve the temperature and humidity of the environment where good price and quality SILICONE STRUCTURAL SEALANT material is used.

With the decrease of temperature and humidity, the problem of adhesion between good price and quality SILICONE STRUCTURAL SEALANT material and substrate is accompanied by slow curing. The general requirements for the use environment of good price and quality SILICONE STRUCTURAL SEALANT products are: a clean environment with a temperature of 10 ℃~40 ℃ and a relative humidity of 40%~80%. If the above minimum temperature requirements are exceeded, the bonding speed will be slowed down and the time for complete bonding with the substrate will be extended. At the same time, when the temperature is too low, the wettability of the adhesive and the substrate surface will be reduced, and there may be imperceptible fog or frost on the substrate surface, which will affect the adhesion of good price and quality SILICONE STRUCTURAL SEALANT material and the substrate.

Solution: When the temperature is 10 ℃ lower than the minimum construction temperature of good price and quality SILICONE STRUCTURAL SEALANT material, the adhesive test shall be carried out for the bonding substrate of good price and quality SILICONE STRUCTURAL SEALANT material under the actual low temperature construction environment, and the construction shall be carried out after the bonding is confirmed to be good.Good price and quality SILICONE STRUCTURAL SEALANT material can also improve the adhesion of good price and quality SILICONE STRUCTURAL SEALANT material by improving the temperature and humidity of the environment where good price and quality SILICONE STRUCTURAL SEALANT material is used
