Instructions for the Use of Curing agent

PUSTAR series inkIt can be used for two-component purposes to enhance the performance of the ink. Curing agent addition: TCS-4394 addition amount: 1-3%

Performance improvement: Increase composite strength, temperature resistance, adhesion, etc

Disposal of old ink: Leftover ink with added curing agent should not be stored for a long time. When using it again, mix it with new ink (old ink <30%) and add the curing agent again. Pay attention to reverse adhesion.

Notes

1.If there are requirements for heat resistance and higher anti-adhesion, 2% to 4% TCS-4394 curing agent must be added for use and cured at 50℃ for more than 48 hours.

2.The surface treatment requirement for the printing substrate is ≥38 dynes. If the substrate is weakly treated for printing, it needs to be confirmed by yourself before use. For printing on films other than the above-mentioned ones or on special films, please contact our company.
