3.

4.

All of the above factors can be avoided.

2.

Due to the large temperature difference between day and night in winter, the low temperature and the drier climate may cause this phenomenon

The above phenomenon only affects the appearance of part of the curtain wall glue joints, but does not produce any bad results on the performance indicators of the colloid.
This phenomenon will be alleviated as the temperature difference becomes smaller
.

Because silicone weathering adhesive has excellent weather resistance and strong resistance to high and low temperatures, it is recommended that it can be constructed under the following conditions:

1.
Please avoid construction in rainy weather, pay attention to the weather conditions during the period of glue application, it is best to have no rain.

2.
When sizing, the glue seam and the substrate contacted by the glue must be dry.

3.
Construction will be carried out during the period from 11 a.
m.
to 3 p.
m.
in winter, and in the morning or evening in summer.

4.
Do a test before construction, squeeze the glue out to observe the curing situation, determine the surface drying time, and trim the surface within the surface drying time
