The application of nail free adhesive in energy-saving building doors， windows， and curtain walls

The application of nail free adhesive in building doors, windows, and curtain walls mainly includes three aspects: secondary sealing of insulating glass, curtain wall structure, weather resistant sealing, and waterproof and weather resistant sealing of doors and windows. The quality of nail free adhesive not only affects the safety of the entire building's doors, windows, and curtain wall structure, but also relates to whether the building meets the requirements of energy conservation and environmental protection.

Hollow glass units have outstanding thermal insulation performance and are an important material for improving the energy-saving level of doors and windows. In recent years, they have been widely used in buildings. The dry gas inside the hollow glass makes it have functions such as sound insulation, heat insulation, anti condensation, reducing cold radiation, and enhancing glass safety.

In the two seals of the hollow glass structure, the first seal is to ensure low water vapor permeability, usually using hot melt butyl adhesive. The second layer of nail free adhesive is used to ensure the integrity of the glass unit structure. Generally, nail free adhesive is used. If it is a hollow glass used for structural assembly, silicone structure nail free adhesive must be selected.
