900CPS Mirror Effect PET Ink,
DIBK Mirror Effect Ink
Mirror-like screen printing ink for PET
Special resin wq-8615 used for product the mirror-effect screen printing inks , has a good adhesion with PET materials, make the electroplated-effect more excellent and obvious. Self-dry after 5 hours at the normal temperature or dry by 10-20 mins’ baking at 100℃,has a good performance in the bending resistance.
Formula A: Screen printing
Great adhesion to cross-cut test and resistance to scraping by fingernail.
Some problems when use
Reason: general speaking, in order to guarantee the good mirror effect of printing ink, the content of resin is relatively low, so that affect the adhesion of ink, which is determined by ink’s characteristics.
Solution: by increasing volume of resin and using hardener agent.
Reason: In order to have good mirror effect, the resin content of mirror-effect ink is relatively low, at the same time, in order to get the normal viscosity of ink, the content of solvent in the ink is relatively high, however, the volatile speed of solvent is so fast and it makes the problem of blocking screen by printing ink. So the mirror-effect printing ink should be printed at fast speed
