Direction for Use
1.Clean up the surface of bonding materials, keep dry and clean. The surface of polyolefin materials must be subjected to a corona treatment or flame treatment.
2.Mix the glue completely 1:1 by volume or 9:10 by weight, we recommend using auto-mix equipment, or the mixed glue should be handled by vacuum system before operation.
3.dispensing the mixed glue to the surface of bonding material,then pressure the two sheets of bonding materials because there is no initial adhesion.
4.waiting over 3 hours under 50℃ or over 8 hours under 23℃, then transfer to the next process.
