High-strength transparent adhesive sealing silicone (transparent sealant for short) is mainly used for the bonding and sealing of lamps, such as the bonding and sealing of LED energy-saving lamps, automotive lamps, automotive LED daytime running lights and other lamps; and the bonding of precision instruments and meters Sealing, such as medical equipment, protective reinforcement and sealing protection of important parts on high-end electronic appliances; of course, various glass, aluminum, stone and metal structural engineering structural bonding and sealing and other industries need bonding or sealing purposes It is also possible to use high-strength transparent adhesive sealing silicone.

Silane coupling agent is an important treatment agent with a wide range of applications. The biggest feature of its molecular structure is that the molecule contains two groups with different chemical properties, one is an inorganic-philic group, which is easy to interact with inorganic substances. A chemical reaction occurs on the surface of a substance; the other group is an organic functional group, which is reactive or compatible with organic substances. Therefore, by using a silane coupling agent, a "molecular bridge" can be set up between the interface of inorganic substances and organic substances, and the two materials with different properties can be connected together to improve the performance of composite materials and increase the bonding strength.

The surface drying time of the transparent silane-terminated polyether sealant decreases with the increase of the amount of the silane coupling agent. This is because the coupling agent contains an amino structure, which plays a catalytic role in the curing of the sealant, which is manifested as surface drying. faster. Therefore, appropriately increasing the amount of silane coupling agent is helpful to improve the surface drying time of the transparent sealant.
