Refer our called about MN Chai GB381 bonding issue.
Please see attached photos.
They are using our GB381 for bonding aluminium to plastic.
Process : Bonding and leave glue cure for 1 night then put in to the rolling to laminate another side by heater.
For this kind of application the bonding area has to passing the roller and heater @175-180C for a few second.
If they are bonding on full panel is no problem but if the bonding area is on the aluminium joining point then that point will delaminate.
They said for SG5000-06 they never found this issue before.
Please kindly advise.
Remark : from photos they are not delamination by heat but customer just break the part to show the bonding area and also not a joining point that they have issue now because one day they may have joining point 1-2 times only.
