High Viscosity Mirror-effect inks Resin for keypad
In almost all inks applications, silver mirror coating finishes
remain a popular choices by stylists.
M8500 super mirror-effect resin used for self-dry paint in
one-component and double-component, clear and dark brightness, good
adhesion,widely used for PET, PMMA, Glass, Reinforced Glass. High
gloss of ink, good printing workability without sand hole and mist,
make real mirroreffect, also used in the glass ink to get the white
and bright mirror-effect by adding common electroplated-effect
aluminum paste.

Some problems when use:
Bad adhesion of mirror-effect ink after printing:
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.
Bad mirror effect of ink after printing:
Reason:
1. Not suitable printing substrate is selected, mirror-effect ink
show the great mirror effect when it was printed in the high
transparent materials such as PET/PC/Glass, but not good mirror
effect in the ordinary materials.
2. In order to increase the adhesion of mirror-effect ink, some
customers add transparent oil or other additives into it, that
affect the mirror effect of ink.
3. When the printing substrate of no resistance to solvent is used,
strong solvent will corrode the substrate and affect the mirror
effect.
Problem of screen blocked by mirror-effect printing ink:
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.
Construction description
Thoroughly stir it before use.
Before spray, make sure the surface of materials clean by dust
elimination, oil disposing, water elimination.
Spray the film evenly, pervious to light is allowed.
In order to make better mirror effect, spraying a layer of
protective paint on the mirror-effect paint is recommended to
enhance the resistance to scratch and antiwear.
Better mirror effect showed in the condition of hot spray(baking
glass to the temperature around 30℃).
Clean and cool working place recommended, high temperature and
humidity or polluted circumstance not allowed.
