Caution

  • As Halogen compounds and polycyclic aromatic hydrocarbons (PAHs) may be mixed in the ink, only designated Solvents and Catalysts can be used.
  • Please check the squeegee rubber, emulsion, materials and substrates before use, as they may contain halogen compounds.
  • In the forming process such as vacuum forming, pressure air forming, and mold forming, as well as in insert molding processes that integrate injection molded resin, a complex set of factors affect the performance of the final product, including the selection of printing materials and inks for design printing, printing conditions, printing sequence, drying method and conditions, selection of molding resin, mold design (gate shape, type and position, number of gates), and conditions set during injection molding.
  • Preliminary testing under actual conditions is strongly recommended before a commercial run.
  • Ink shelf life: 24 months from production date, unopened.

Safety

  • UN No.: 1210
  • UN Classification: Class 3 Flammable Liquids (Flash point is over 23 Degree C)

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

What is the meaning of FIM/IMD?

The abbreviations, FIM and IMD, stand for Film Insert Molding and In-Mold Decoration. For these methods, the printed film is set into the mold and molded with molding resin as the finished product.

We recommend reading the FIM/IMD technology White Paper:
(1) FIM/IMD – 3 Process stages & Benefits
(2) FIM/IMD – Screen printing process –
(3) FIM/IMD – Forming process –
(Final) FIM/IMD – Injection process –

We recommend reading the following reports:

Using FIM/IMD method, can you give us some examples of substrate film and molding resin combinations?

PC, PET, and Acrylic substrate sheets are suitable. Suitable resins are PC, PMMA, PC/ABS, AS, etc. However, PP and Olefin are currently difficult to use because they do not have good adhesiveness to the substrate materials.

What is the difference between Film Insert Molding and In Mold Decoration? Do you use different inks for each?

For the FIM method, the printed surface will be placed between the substrate sheet and the resin. On the other hand, for IMD method, the printed surface will appear on top of the adhered layer of the substrate sheet and the resin. The type ink will depend on the application and your requirements.

What is the largest size that you can use for the Insert Molding Method?

Theoretically, it depends on the capability of molding machine. However, there is an elongation limit of the substrate sheet; it varies depending on the printing materials you are using.

Can you give some examples of the type of industry where a combination of ink and molding method is being used? What would be the actual finished product?

The main industries will be automobile interiors, amusements, and home appliances. Their finished products are such items as speedometers, pinball game machines, water boilers, TVs and possibly as cover material in various other areas.

Do you have any restrictions when you use functional inks for molding inks?

There are some limitations of color hue, glossiness, and other properties. Sometimes, Teikoku Inks is unable to meet a customer’s requirements due to the design of the product.

We found that sometimes when we peel off the print from the injected resin, ink remains on one side or sometimes on both sides. Why does this occur?

In the case of ink remaining on the substrate, adhesion to the injected resin is poor. When ink remains on the injected resin, the adhesion to the substrate is poor. This is delamination. When ink remains on both sides, adhesion to substrate and injected resin are good, but the cohesion of the ink layer is poor. This is a cohesion failure.

The printed layer peeled away from the injected resin. What should we do?

This may be due to a mismatch of ink, substrate and the resin. Please contact our representative.

We have always had good adhesion, but suddenly peeling has occurred. What should we do?

Ink attached so far but it suddenly peeled off. I don’t know what to do.
Please check the following.
(1) Film thickness of printed ink layer
Thinner binder layer tends to have weaker adhesion.
(2) Drying conditions for printed ink layer
If ink doesn’t dry sufficiently, the strength of the printed ink layer becomes weak and cohesive fracture will occur.
(3) Are there any additives such as defoamer contained in ink or binder?
If additive such as defoamer is added in ink, ink’s adhesion to resin tends to be weak.

What are the meanings of X and Q used in the ink names such as IPX, INQ, FMX, etc.?

X and Q are used to designate isophorone-free inks.

What is non-conductive black ink?

Non-Conductive Black Ink is an ink that has a high electrical resistance of the printed ink layer, and has both a function that is difficult for electricity to pass through and a high opaque black color. The high electrical resistance (low conductivity) prevents malfunctions and failures of electronic components, etc., caused by electric current flowing through the printed ink layer. Furthermore, its high opacity makes it suitable for printing on flat panels and smartphone displays that require light-shielding properties.
