This was mixed with EVA (100 g/h) in an extruder to obtain a dispersion containing EVA 53% and a pH of 8. 10 parts (parts by mass) of the dispersion were mixed with 90 parts (parts by mass) of the PVC dispersion (the two parts were evenly measured in terms of solids) to obtain a binder.
Use The glue is used for heat sealing bonding of PVC containers and their lids.
