High Temperature Takes over The Stage of Weather, And The 'change And Defense' of Glass Glue

The weather in August is always full of drama. Just as the raging typhoon has passed, high temperatures eagerly take over the weather stage.

According to the forecast of the China Meteorological Administration in August 2025, temperatures in most regions of the country are close to the same period of the year and may be higher than usual. Among them, the number of days with high temperatures (≥ 35 ℃) in East China, Central China, and southern Xinjiang is higher than that of the same period of the year, and the risk of periodic heatwaves is significantly increased.

In this high-temperature "baking" test, the performance of glass glue quietly changes.

However,  CSJ-368 fireproof and flame-retardant sealant adheres to the defense line of safety and quality with its unique advantages.

High temperature "baking" test | "transformation" state of glass adhesive

1. The "fast and slow" drying speed

•In high temperature environments, the drying time of glass glue will be significantly shortened. Normally, when the room temperature is between 20 and 25 degrees Celsius, ordinary glass glue takes 24 to 48 hours to completely dry. But when the temperature rises above 30 degrees Celsius, the drying time may be shortened to 12 to 24 hours.

•Humidity is also a key factor affecting drying time. It is crucial to ensure good ventilation in the construction environment during August weather, as this can accelerate the evaporation of solvents in the adhesive and shorten the drying time.

2. The "strength and weakness" of adhesion • High temperature has a direct impact on the adhesion of glass glue. When the temperature exceeds the tolerance range of the glass adhesive, its bonding strength will significantly decrease, resulting in a significant reduction in sealing performance. These changes will make the glass adhesive unable to effectively block the intrusion of air, moisture, and dust, thereby affecting the service life and safety of the building.

3. The chemical stability of glass glue is the key to its ability to maintain long-term sealing performance. But under the continuous "attack" of high temperature, the chemical bonds inside the glass adhesive may break or recombine, leading to a decrease in its chemical stability.

Glass glue that is exposed to high temperatures for a long time will gradually experience discoloration, hardening, and other phenomena. It may even release harmful gases such as formaldehyde, benzene, etc., causing serious pollution to indoor air quality and endangering human health.

Genesis CSJ-368 | The "Way of Guarding Glass Adhesive"

1. The "tough" shield Genesis CSJ-368, which is resistant to high temperatures, can withstand high temperatures and can be used in high-temperature areas such as pipelines, wall joints, chimneys, fireplaces, etc., with significant effects. CSJ-368 can maintain stable performance even at high temperatures, without losing adhesion or experiencing aging, cracking, or other issues due to temperature rise, providing reliable sealing protection for buildings.

2. The fire-resistant and flame-retardant "moat" not only has high temperature resistance, but also has excellent fire-resistant and flame-retardant properties in CSJ-368. It is equivalent to a non combustible medium that can effectively prevent the spread of fire. When encountering a large fire or high temperature, CSJ-368 will not transfer heat to the human body or other objects, which can reduce the harm caused by the fire.

The use of CSJ-368 in important areas such as pipes, channels, and fire partitions inside buildings can form a sturdy fire "moat" to protect people's lives and property.

3. The "green" color of Genesis CSJ-368, which is environmentally friendly and low VOC, meets national environmental standards and has low VOC (volatile organic compound) emissions. It can reduce indoor air pollution and create a healthy and comfortable living and working environment for people.

4. Tips for High Temperature Construction • Choosing the Right Construction Time To avoid the impact of high temperatures on glass adhesive construction, it is advisable to choose construction during relatively low temperatures in the morning and evening. The temperature is low in the morning, and the flowability of the adhesive is good, making it easy to operate; In the evening, the temperature gradually decreases, which is also conducive to the curing of glass glue.

•Preparation work before construction should be done in advance by conducting compatibility tests to ensure good adhesion with the materials being constructed. At the same time, ensure that the surface of the construction material is clean and free of oil stains, creating favorable conditions for the glass adhesive to perform at its best.

•Reasonably controlling the thickness of the adhesive layer directly affects its drying time and sealing effect. Under high temperature conditions, it is advisable to avoid applying too thick to accelerate the drying process.

The high temperature in August is a severe "baking" test for glass glue, and ordinary glass glue may expose many problems in this test. Genesis CSJ-368 fireproof and flame-retardant sealant has become an ideal choice in high-temperature weather due to its advantages of high temperature resistance, fireproof and flame-retardant properties, and low VOC environmental protection.
