3 Hardening of adhesive: Notes
The adhesive hardens by reacting with air humidity at room temperature.
IMPORTANT:
Once the adhesive bead has been applied, the window glass must be installed within 7 minutes (depending on air humidity, temperature).
After 7 minutes the adhesive bead forms a skin which can no longer guarantee a perfect bond.
After 7 minutes the adhesive bead forms a skin which can no longer guarantee a perfect bond.
At ambient temperatures above 23 °C and 50 % relative air humidity (hot countries), the adhesive open time is shortened to approx. 5 minutes (skin formation time).
A relative air humidity of < 30% significantly slows hardening.
The adhesive hardening process is interrupted completely at ambient temperatures below 5 °C. In this event, there will be no increase in the strength of the bonded connection.
