Specific requirements for the use of silicone adhesive

Silicone adhesive is a type of ointment that, once exposed to moisture in the air, solidifies into a tough rubber like material. It is widely used in daily life. Today, we will introduce its specific usage requirements.

1. Fixed to the metal frame of the glass, the glass receives wind loads, earthquakes, weight and temperature changes and other environmental efforts are estimated through gel to the metal frame, which is necessary to select the neutral structural glue of the silica gel.

2. The main weather sealants are silicone sealant, chloroprene sealant, and polysulfide sealant. The differences between them should not be mixed or used together. Weathering sealant is mainly used for external sealing of buildings, with resistance to atmospheric changes, UV radiation, and aging being the main policy considerations.

3. The same curtain wall project should use the same brand of one component or two component silicone sealant, and use the same brand of matching silicone weather resistant sealant; Sealant strips shall not be used, but expired structural sealant shall not be downgraded to the application of weather resistant sealant.

4. The procurement of structural sealant is necessary, and careful inspection, compatibility testing, and functional touch materials should be carried out.

5. After the construction is completed, the silicone sealant and silicone weather resistant sealant for the structure have been completed, and it is necessary to ensure their application range within the validity period.

6. Soft, colored, and transparent silicone sealant has poor UV resistance and is only suitable for indoor engineering. Generally, black should be chosen for outdoor applications.

7. The storage environment for adhesive should meet the temperature and humidity requirements.
