  • Home Appliance (IoT)

  • Smartphone, Tablet, Smart watch

  • Sensor

  • Game

  • Others

Features, Function

  • No intentional use of Halogen (Chlorine Cl, Bromine Br) compounds in raw materials.
  • High thixotropy, suitable viscosity for printing, and excellent printability.
  • Capable of producing a clear, spots-free, mirror-finish ink layer.
  • Mirror

Substrate

  • PC and Treated PET film
  • PC
  • Easy adhesion treated PET

Dilution

  • C-002 SOLVENT
  • Dilution: 0 to 10%
  • *Basically, no dilution is needed. Do not use other solvents as they may adversely affect mirror surface, adhesion, stencil stability, and other properties.

Catalyst, Promoter mixing

  • 106 CATALYST 1%（to improve adhesion）Pot life: 4 hrs.
  • 200 CATALYST 3%（for insert molding）Pot life: 4 hrs.
  • *Use catalyst to improve adhesion to hard-to-bond substrates（hard coat substrates, etc.） and for insert molding applications. Please mix only the amount to be used.

Recommended cleaner

  • Screen Cleaner L2

Mesh

  • T 300 mesh（Coverage is about 40-50m2/kg）

Drying

  • 80℃ 30 min
  • Over print
    MIR　 　 80℃　30 min
    Back print 　80℃　30 min

Caution

  • Although Mirror Ink itself adheres to the substrate, be sure to overprint to prevent scratch and to improve gloss and resistance.
  • Use “MIX-HF or MIB Ink series” for back print. For recommended printing conditions, please refer to the respective ink catalog.
  • If the ink layer thickness is 3μm or more, delamination may occur between mirror ink and the back-print ink.
  • Heated drying is strongly recommended. More than 30 min at 80℃ is necessary. Delamination may occur if MIX-HF or MIB ink is back-printed and dried without the mirror ink having dried.
  • Be sure to conduct preliminary tests to check the mirror surface and adhesion before carrying out mass production tests.
  • Ink viscosity increases after printing. Do not add used recovered ink to unused ink, unless transfer it to another container, add C-002 solvent and dilute to the viscosity of unused ink before use. However, when using recovered inks, please check the print finish, etc. in advance.
  • Ink shelf life: 6 months from production date, unopened.

Handling

  • Use safety gloves and eyeglasses to protect skin and eyes. If the ink comes in contact with skin, wash with soap and plenty of water (or lukewarm water) and consult with a doctor.
  • Containers should be closed tightly after use and stored in a cool and dark place.
  • SDS is available upon request. Please request a copy and read it carefully before handling the products.

FAQ

How can we increase covering power?

Use squeegee with 70 degree hardness and rather high printing pressure. When printing with Mirror Ink, the covering power may not be as good as what is shown in print samples. An effective measure to increase covering power is to use a harder squeegee. As the Mirror Ink has less resin in it, ink transfer to the substrate is rather lighter than with ordinary screen inks.

Therefore changing printing conditions is sometimes effective.

* Recommended printing conditions are as follows
Squeegee hardness should be 70 degrees. / Printing pressure should be slightly higher. / Doctor pressure should be slightly higher as well.

Is over-printing required?

Yes. Over-printing is necessary not only to improve scratch resistance but also to improve resistance to other elements. As Mirror Ink is affected by moisture, the aluminum layer might change the color if not over-printed.
