Insulating Glass
The most used way to seal two pieces of glass is the double channel sealing structure. Firstly, two pieces of glass are separated by article interval, and the gaps between the glass and the article interval are sealed by butyl rubber to prevent moisture transferring into airspace. Then, the gaps between the glass edge and article internal should be bonded by the secondary sealant to hold unit together. The secondary seal mainly adopts silicone sealants.
Silicone sealants are formulated with different functional group structures in the organic silicon polymer main chain, they have stable structure and can keep the performance level of their initial specifications for many years. Meanwhile, they have the advantages of moisture-proof, UV-resistance, anti-corrosion, high and low temperature resistance and strong tensile strength. In brief, silicone sealants can keep the structure of insulating glass stable and prevent it from aging.
