MIR-51000 Mirror Silver (Mirror Effect Screen Ink for PC and Treated PET Film)

MIR-51000 Mirror Silver Screen Printing Ink provides excellent printability for PC and treated
PET film. It is also eco-friendly since chlorine vinyl acetate copolymer is not used in this
product. It can replace metal plating, which results in eco-friendly products at competitive
prices, and is applicable for home electric appliances, mobile phones, etc.

Provides mirror-like effect on PC and/or treated PET film. Replaces metallic films, hot
stamping foils and metal plating.
Applicable for display panels of home electric appliances, numeric keypads for mobile phones,
membrane switches and other products.

Excellent Printability:
MIR-51000 has excellent printability with suitable viscosity and thixotropy compared with MIR
9100 mirror Silver. It is also applicable for various printing designs such as convex letters and
solid letters.
Excellent mirror finish :
Compared with MIR-9100 Mirror Silver Ink, MIR-51000 provides a excellent clear mirror finish
with no blur.
Eco-friendly: Eco-friendly since no hazardous substances such as metal plating or chlorine
vinyl acetate copolymer are used.

Basically, no thinning is needed. However, if needed, use C-002 solvent. Do not use any
other solvent since it may damage adhesiveness, mirror effect, etc.
Please use Teikoku Screen Cleaner N for cleaning.

Following are the printing conditions for the MIR-51000 Ink:

Stencil Mesh: T-300 Mesh
Thinning: No thinning needed; printable without thinning
Drying: More than 30 minutes at 80℃ (forced drying)
Catalyst: No hardener needed; printable without hardener. However, use hardener when printing on poor adhesion substrates and/or for insert molding applications.

• When printing on poor adhesion substrates, use 106 Catalyst. When using 106 Catalyst, the ratio (MIR-51000:106 Catalyst) is 100:1
• For the insert molding application, use 200 Catalyst. When using 200 Catalyst, the ratio (MIR-51000:200 Catalyst) is 100:3.
  Add Catalysts just before printing and mix well.
  

Before using, it is important to stir the ink well as ingredients may have separated over time.
Coverage of 40-50m2/kg can be expected with T-300 mesh.

 

MIR-51000 itself adheres to the substrate, but in order to improve scratch-resistance, the
degree of brilliance and other resistance properties, overprinting is strongly recommended.
Teikoku’s MIB Series of inks are recommended for the overprint ink.
The thickness of the dried ink should be less than 3 microns, otherwise the Mirror Ink layer
might be delaminated.
For the squeegee, 70-80 degree hardness and 70-80 degree angle are recommended.

Heated drying is strongly recommended. More than 30 minutes at 80℃ is required.
If the MIB ink is printed as an overprint before the Mirror Ink is dry enough, the Mirror Ink
layer might be delaminated.

Print overprint ink after printing MIR-51000 in order to improve scratch-resistance, the degree
of brilliance and other resistance properties although MIR-51000 itself adheres to the substrate.

Teikoku’s MIB Series of inks are recommended for the overprint ink.

Printing conditions when overprinting with MIB Ink are:

Stencil Mesh: T-250 to T-300 mesh
Thinning: F-002 or F-003 solvent at 15% (recommended). Do not use any other solvent since it may damage adhesiveness, mirror effect, etc.
Drying: 30 minutes at 80℃
Catalyst: 240 Catalyst
Additive amount of the Catalyst: (MIB Ink:240 Catalyst) is 100:10

For standard colors, please refer to the product information of the MIB Ink Series. If
color-matching of the MIB Ink Series is needed, please contact Teikoku.

Before a commercial run, preliminary tests must be done at your site under actual conditions to
check the mirror effect and adhesiveness.

Viscosity of the residual ink on the stencil will be higher than the virgin ink. The residual ink
should not be mixed with the virgin ink. It can be collected in a container and reused after
reducing the viscosity to that of the virgin ink with C-002 solvent. Moreover, before using the
collected ink for a commercial run, please check the finish of the coating first.

Flammable;   UN Class: Not applied;   UN No.: Not applied

Use safety gloves and eyeglasses to protect skin and eyes. If the ink or coating contacts the
skin, wash with plenty of water and soap. In case of contact with eyes, wash with plenty of
water and consult with a doctor.

Containers should be tightly closed immediately after use and stored in a cool, dark place.

MSDS is available. Please ask for a copy and read it carefully before handling materials.

Please follow all instructions carefully and use all ink products responsibly.
