2.Applicable model:
Applicable on various speeds laminating machines.
100 ℃/30 minutes plastic water boiling sterilization
Fast curing speed
Wide range of coating concentration (25%~45%) and low adhesive cost
Not suitable for composite of PE films with high content of additives
3.Recommended ratio:
20:4. The actual environmental humidity and printing ink have a significant impact on the laminating effect. Customers should adjust the amount of curing agent appropriately according to the actual situation
4.Operating conditions:
(1) When diluting, add the solvent to the main agent according to the required solid content, stir it thoroughly,
(2)Then add the curing agent, and stir it evenly before use.
(3) The water content of the solvent ethyl acetate shall not exceed 0.03%, and the alcohol content shall not exceed 0.02%
(4) Working concentration 25%~35%
5.Drying:
The drying device should have sufficient air volume, wind speed and temperature. When the drying system is divided into three sections, the temperature from the membrane inlet to the outlet is controlled between 50~60℃, 60~70℃, and 70~80℃.
