In order to ensure the quality of injection processing, the two-component glue maker suggests that the following preparations should be made before the use of hollow glass two-way sealant (hollow glue for short):
A: Requirements for use and maintenance environment: Hollow glue injection area should be clean, dust-free and ventilated, the temperature should be maintained at 10-40 C and the relative humidity should be 40-80%. The temperature of hollow glue itself should not be lower than 10 C before use, and when the storage temperature is relatively low in winter, it should be placed in the heating room for several days before use, at the same time, hollow glass should be maintained. The temperature in the zone should not be less than 10 C.
B: Requirements for the surface of the base material: All the adhered parts of the base material should be cleaned to remove dust, oil or other dirt; when making hollow glass by off-line low-radiation coated glass processing, the edge sealing area of the base material should be removed first.
Experience sharing: The curing of hollow adhesive is a chemical reaction process. Temperature has a great influence on its curing process. The suitable use environment and maintenance environment are important environmental factors to ensure the best curing and bonding properties of hollow adhesive. The dirt and dust will affect the final bonding performance. Therefore, the surface of the bonded substrate must be cleaned. Low radiation coated glass has poor compatibility with structural adhesives. In order to ensure good adhesion between hollow adhesives and glass, it is suggested that the coated glass should be removed first in the process of processing.
