Sealant application step

The applied sealant must be filled into the entire interface and tightly adhered to the surface of the substrate that needs to be in contact with the glue. If the sealant does not completely fill the interface, it will not have good adhesion and the performance of the glue will be weakened. In order to get good adhesion, the glue needs to have a clean, dry, frost-free surface. Although silicone rubber has a wide application temperature range and can be easily applied, the actual construction temperature is limited by whether the interface surface is frosted, that is, when the temperature is lower than 4 C, the frosted surface is cleaned. The solvent is preferably a water-soluble solvent such as IPA.
