LOW-TEMPERATURE PRESSING METHOD FOR PRODUCTION OF INSULATING GLASS PACKETS Russian patent published in 2009 - IPC C03C27/10 B32B17/10 

FIELD: construction.

SUBSTANCE: sealant composition hardened by moisture is applied onto the first surface of spacer and second surface of spacer. Sealant compositon contains from 5 wt % to 80 wt % of amorphous poly-alfa-olefin with silane-functional group, from 5 wt % to 40 wt % of butyl rubber, at least from 10 wt % and not more than 70 wt % of polyisobutylene and from 5 wt % to 60 wt % of adhesive agent. Sealant composition is contacted on the first surface of spacer with the first window glass, and is also contacted on the second surface of spacer with the second window glass. Pressure is applied to packet at ambient air temperature of around 15°C-60°C for binding of the first glass panel with the spacer by means of sealant and for binding of the second glass panel with spacer with the help of sealant.

EFFECT: lower temperature and pressure, at which glass panel binds with spacer with the help of sealant.
