Construction requirements of silicone weather resistant adhesive

1. Temperature requirement

The temperature requirements of silicone weather resistant adhesive are relatively harsh. Too low a temperature will affect its curing speed, too high a temperature will affect its adhesion and shape retention, but also lead to increased colloidal fluidity, difficult to control. Therefore, pay attention to the ambient temperature during construction. It is recommended to work at an environment of 15℃ to 30℃.

2. Humidity requirement

Silicone weather resistant adhesive also has high humidity requirements. It is generally required that the construction environment humidity is between 50% and 70%. Too high humidity will lead to incomplete colloidal curing, while too low humidity will lead to too fast drying speed of silicone weather resistant glue, difficult to construction. Therefore, it is necessary to reasonably control the humidity of the construction environment before construction.

3. Oxygen requirement

Silicone weather resistant adhesive needs to be fully in contact with oxygen during use so that it can fully react and cure. Therefore, it is necessary to ensure sufficient oxygen supply in the construction environment when using to avoid the colloid cannot cure.

4. Ultraviolet requirement

Ultraviolet can affect the chemical reaction and properties of silicone adhesive. Therefore, in the construction process to avoid the colloid long-term exposure to strong ultraviolet environment. Long-term exposure to ultraviolet light should also be avoided after construction, so as not to affect its durability and performance.

In summary, the environmental requirements of silicone weather resistant adhesive are very important. It has important influence on construction quality and use effect. If you need to use silicone weather resistant adhesive, please be sure to pay attention to its requirements, and understand and master its use methods and precautions before construction to ensure that the construction quality and use effect achieve the desired effect.
