CURING
| Curing temperature(℃) | 50±5 |
Curing time(hrs) | 24-48hrs (At least 24hrs of curing for the pre-laminated films is required before the completion of rewinding or laminating of the 3 layer composite film. And It is needed to process the pouch making after the completion of curing perfectly.) |
INSTRUCTIONS
●It may experience interactions with the ink of the pre-laminated composite material, the film additive or the substance of coating layers or the stuff of packing. (esp. below-mentioned substances in higher content: e.g. vinyl acetate in polyethylene film, slip agent, antistatic agent, antimist additive, pigment, etc. ) Therefore it is necessary to examine the interaction of adhesive solution and the composite materials before mass production.
●It is necessary to increase the dosage of curing agent when laminating the polyurethane ink printed materials with no hardener is performed. A test referred to the properties being able to reach the requirement of the quality must be made before mass production.
