MF910/ MF910G/MF910T Insulating glass with butyl hot-melt sealant: used for the first sealing of insulating glass, it can form an excellent anti-moisture system together with elastic sealant.
Insulating glass (channel aluminum type) must adopt a double-sealing method to ensure its sealing and durability. That is to say, the first seal adopts hot-melt butyl sealant, which is mainly used for sealing; the second seal is completed by elastic sealant, which plays the role of auxiliary sealing and maintaining the stability of the insulating glass structure. The two complement each other and are indispensable.
At present, most of the hot melt butyl sealant products on the market, whether imported or domestic, are mostly black in color. Our company has also developed transparent, gray and white hot melt butyl sealants.
