Insulating glass butyl Sealant

1: for the primary sealing of the insulating glass
2: outstanding adhesion to aluminum and glass
3: good vapour resistance.
Description
JOINLEADER900 is butyl sealant designed for use as the primary moisture barrier in dual sealed insulating glass units. It exhibits low argon permeability, excellent adhesion to glass and aluminum, good compressibility,and inherent moisture vapor resistance.

Application
It can be used for the manufacture of insulating glass units. Together with an elastic sealant compound like silicone, polyurethane or polysulfide sealant, they form an excellent dual-seal system.
