A、 Recommended construction temperature and storage conditions

The performance of conventional silicone sealant, such as curing speed, adhesion, elasticity, etc., is greatly affected by temperature and humidity.
When the surface temperature of a general building is below 4 ℃ or above 40 ℃, construction should not be carried out, and it needs to be stored in the original packaging in a cool and dry place below 27 ℃.

B、 If construction is carried out in a low-temperature environment, we recommend:

In the cold and low-temperature northern climate environment, Gaolide recommends using "8809 Low Temperature Rapid Drying High Performance Silicone Weather Resistant Adhesive" for construction. This low-temperature weather resistant adhesive meets the product standard of GB/T 14683-2017 and can support construction at temperatures above 5 ℃ and humidity above 50%. It also provides 6-hour quick drying flipping and is suitable for various door and window installations, non structural waterproof sealing of glass assembly joints, waterproof sealing between heavy-duty sliding doors, middle window glass, window frames and walls, and indoor decoration bonding sealing in low-temperature weather in the north, accelerating high-quality delivery.

C、 Precautions for construction in cold or hot weather

1. Precautions for construction in cold weather (low temperature)
The key to construction in cold environments is to ensure that the weather resistant sealant can cure properly and achieve good bonding.

Grassroots treatment is crucial: before construction, the surface of the base must be thoroughly cleaned of moisture, frost, and snow. Damp and frozen substrates can affect the bonding effect.
Material and base temperature: It is recommended to place Gaolide 8809 quick drying adhesive in a warm indoor environment (such as above 10 ℃) before construction, and then remove it when in use. If conditions permit, appropriate preheating can be applied to cold metal, glass, and other substrates to improve adhesion.
Pay attention to curing time: Low temperature will significantly prolong the curing time of the sealant. Longer curing time needs to be reserved to avoid applying stress or proceeding to the next process before the colloid is completely cured.

2. Construction precautions in hot weather (high temperature)
In high-temperature environments, the challenge lies in controlling the curing speed and preventing colloid flow.

Adjust construction time: Try to avoid the hottest and most sunny periods of the day (such as noon to afternoon). It is more suitable to carry out construction in the early morning, evening, or night.
Properly store materials: Store the sealant in a cool, dry place, away from direct sunlight. High temperature can accelerate the vulcanization of sealant, and high temperature weather may shorten its storage period.
Base cooling treatment: Before gluing, the base layer (such as aluminum plate, glass) that has been exposed to scorching heat can be sprayed with water to cool down (wait for the surface to dry before construction) or avoid the highest temperature period to prevent the surface from skinning too quickly, producing bubbles or sagging after the colloid comes into contact with the high-temperature base layer.
