Recipe of Heating SGP INTERLAYER Laminated Glass in EVA Vacuum Ovens
Please note that Not all EVA vacuum oven can laminate SGP interlayer, some can, some can not.
【1】The EVA ovens may work slightly differently, so you need to do some adjusting by yourselves based on real situations.
【2】Vacuum pressure: should be stronger than 101 kPa
【3】Low temperature stage:
Cold vacuuming for 5 mins
10mins heating up to 65℃
Holding at 65℃ for 30mins
【4】High temperature stage(Cooking time) : at 135 degrees C for 3.5 hours
【5】Always put only one piece of pre-SGP laminated glass per vacuum bag, you can not stack or place multiple pieces in one bag(or you may have bubbles problem).
The above data is based on [6mmGLASS+0.76mmSGP+6mmGLASS], if you laminating thicker interlayer or thicker glass, please keep the same temperature, but prolong the holding time for high temperature stage by 10-30mins.
