Precautions for Using Glass Glue in High Temperature Weather

Glass glue is a room temperature curing adhesive that is greatly affected by the environment. The temperature keeps rising in summer, and the humidity in the air keeps increasing. The curing of sealant depends on the humidity in the air, so changes in temperature and humidity in the environment will have a significant impact on the use of products such as silicone sealant.

The high temperature in summer causes the surface temperature of the substrate to become very high during outdoor construction. When the glass glue solidifies, the temperature of the bonded material cannot exceed 50 ℃. Once the surface temperature of the substrate exceeds 50 ℃, injecting glue will cause bubbles in the adhesive joint.

The above situation is often encountered during the construction of joint filling. When the temperature is too high, construction should be carried out in the evening or on cloudy days to avoid foaming caused by high substrate temperature.

If construction cannot be avoided under these conditions, it is recommended to conduct a small-scale adhesive test and a peel adhesion test before use to confirm good adhesion and no adverse phenomena before large-scale use. In addition, measures such as sun shading and explosion prevention can be taken appropriately during the construction process to reduce the occurrence of bubbles and bulges.

What should be paid attention to when using glass glue in hot summer? Today, the editor will share with you:

Storage precautions

01

Matters needing attention

The high temperature in summer also has certain requirements for the storage of glass glue. It is recommended to store the glass adhesive in a ventilated, dry, and cool place, avoiding direct sunlight. Meanwhile, it is important to avoid placing it near flammable materials to prevent fires.

Dry and sealed storage, isolate air and water, pay attention to secondary sealing of opened glue, keep the storage environment dry, and avoid water vapor infiltration that may cause silicone glue to deteriorate and affect the sealing effect.

Precautions for use environment

02

Matters needing attention

When using glass glue, attention should be paid to the usage environment. When used in high temperature environments, certain treatment is required for the glass adhesive. For example, glass glue can be left to stand in a cool place for a period of time to reduce its stickiness.

At the same time, avoid operating under strong light during use to avoid affecting the viscosity of the glass adhesive.

Precautions for usage

03

Matters needing attention

When using glass glue, the correct usage method should be followed. First, apply the glass adhesive to the area to be bonded, and then wait for it to dry. Due to the high temperature in summer, the drying time of glass glue may be shortened.

Therefore, after applying glass glue, it should be left for sufficient time to dry. Finally, it is important to avoid squeezing the glass adhesive before it dries to avoid affecting its effectiveness.

The high temperature weather has brought many inconveniences to various operations. In order to ensure the progress of the project, the construction and production masters are still sweating on their posts. Genesis reminds everyone to pay attention to heatstroke prevention and sun protection to ensure their own safety.
