V. matters needing attention
Suggested natural curing after printing, then examines, the compound aged after 50 to 60 ℃ for 24 hours, room temperature placed after the bag again.
Curing agents are usually added at 10-11% of the weight of the original ink, and diluted water-based printing inks are added for quick mixing.
N-butanol, butyl acetate has a big smell, should ensure that printing materials to dry, try not to use, avoid printing solvent residue too high.
The humidity on the printing site should not be too high, and ventilation should be maintained.Avoid excessive humidity caused by ink thickening precipitation and printing ink layer surface absorption of moisture in the air, resulting in the ink layer surface flour and no adhesion.
For other requirements, please contact our technical department.
Ink must be sealed and stored in a cool place, effective shelf life of three months, diluted ink use as soon as possible, to avoid long storage.
After the addition of curing agent, the remaining dumb oil should be stored as thin as possible (it can be stored for one month) to prevent solidification. Filter it before use next time, and then add 1%~2% curing agent or an appropriate amount of new dumb oil for normal use.
