4、 Usage process and precautions：
1. Clean the surface: Clean the surface of the adhesive or coated material to remove rust, dust, oil and other pollutants.
2. Glue application: Unscrew (or peel) the rubber tube cap, squeeze or spray the glue onto the cleaned surface, and make it evenly distributed.
3. Curing: Place the adhesive component in air to allow it to naturally cure. The curing process is a process of curing from the surface to the inside. Within 24 hours (at room temperature and 55% relative humidity), the adhesive will cure to a depth of 2-4mm. If the application position is deep, especially in areas that are not easily in contact with air, the complete curing time will be extended. If the temperature is low, the curing time will also be extended. It takes more than 7 days for a 6mm thick sealant to fully cure. For potting with a thickness greater than 6mm, it is recommended to use tomorrow's two component potting adhesive.
4. After the operation is completed, the unused adhesive should be immediately tightened and sealed for storage. When reusing, if there is a slight crust at the sealing area, it can be removed without affecting normal use. During the storage process of the adhesive, there may also be a small amount of solidification at the nozzle, which can be removed for normal use without affecting product performance. If it accidentally enters the eyes before solidification, seek medical attention.
