How To Insulate And Moisturize Glass Glue During Winter Construction?

With the gradual decrease in temperature, many people have begun to pay attention to the impact of cold weather on building materials, especially glass sealants. Glass sealant, as an important material for connecting glass and substrate, is easily affected in cold weather, thereby affecting its sealing effect and service life.

Firstly, cold weather can cause a decrease in the viscosity of glass sealant. The viscosity of sealant is the key to its sealing performance, and low temperature will slow down the movement of polymer molecules in the sealant, resulting in a decrease in viscosity. This may result in inadequate sealing, leading to issues such as water and air leakage.

Secondly, cold weather can increase the difficulty of applying glass sealant. Due to the slower curing speed of sealant at low temperatures, it takes longer to achieve the desired curing effect after construction. In addition, workers operating in low-temperature environments may also be affected, which can lead to improper construction. To ensure its good bonding effect and curing performance, it is recommended that everyone take certain insulation and moisturizing measures. Here are some specific suggestions summarized by the editor:

Thermal insulation measures

1. Increase the temperature of the construction environment

Use heaters, radiators, and other equipment to increase indoor temperature and ensure that the construction environment temperature is within the suitable working range of the glass adhesive, usually recommended to be above 10 degrees Celsius. Avoid glass glue construction outdoors or in rooms with low temperatures.

During the construction process, ensure good sealing in the construction area and avoid direct cold air blowing on the construction surface, which may affect the curing effect of the glass adhesive.

3. Choose glass adhesive with good weather resistance. The weather resistant adhesive has undergone artificial accelerated climate aging testing and has excellent weather and aging resistance, excellent adhesion, and high and low temperature resistance. Choosing weather resistant adhesive during winter construction can ensure its stable bonding effect even in low temperature environments.

Moisturizing measures

1. Control the humidity of the construction environment

In winter, indoor humidity may be lower, which can affect the curing speed and bonding effect of glass glue. Therefore, humidifiers or other methods can be used to increase indoor humidity appropriately to ensure that the construction environment has suitable humidity.

2. Avoid ventilation immediately after construction. 

After construction is completed, do not open windows for ventilation immediately to prevent rapid decrease in indoor humidity. You can wait for a period of time for the glass adhesive to solidify in a relatively stable humidity environment.

3. Improve the retention of substrate moisture

Before construction, it can be ensured that the surface of the substrate maintains a certain degree of moisture, which helps to bond the glass adhesive to the substrate. But be careful not to excessively wet it, so as not to affect the curing effect of the glass adhesive.

During winter construction of glass adhesive, a series of insulation and moisture retention measures need to be taken to ensure its good bonding effect and curing performance. By increasing the temperature of the construction environment, preheating the glass glue, selecting glass glue with good weather resistance, and controlling the humidity of the construction environment, the challenges of winter construction can be effectively addressed.
