China One-Component Insulating Glass Hot Melt Sealant

Hot melt Sealant for Insulating Glass

Application Field:
One component,solvent free, non­fogging, permanently plastic butyl sealant , formulated for primary sealing of insulating glass units.
It can keep its plastic and sealing properties in a wide temperature range.
Excellent adhesion properties on glass, aluminum alloy, galvanized steel and stainless steel.
Minimum moisture vapour and gas permeation.
Excellent temperature stability: - 30.C to 80ºC
GLASS I SPACER - To achieve good adhesion,
the glass/ spacer surface must be clean, dry and free of any residue.
Product Introduction :
Butyl adopts the imported butylene as the main raw materials, has the strong adhesive and joint characters to IG and spacer bars, good weathering resistance, can bear high temperature, low moisture,vapor and gas transmission rate.It is the first barrier for the insulated glass sealing process. Conform to the JC/T914-2014 standard.
