Product overview

TOC-HF Ink forms a transparent colored ink layer, which can be overprinted with MIR-51000 Mirror Silver to obtain a mirror effect surface with vivid colors. It is environmentally friendly ink for molding that does not intentionally use halogen compounds (chlorine Cl, bromine Br) in raw materials and does not contain environmentally hazardous substances such as benzene, toluene, xylene, and isophorone.

  • Do not use solvents and catalysts other than the designated ones because of the possibility of contamination with halogen compounds.
  • Please check the squeegee rubber, emulsion, materials and substrates before use, as they may contain halogen compounds.
  • In the insert molding, in which the printing sheet is inserted inside the mold and is integrated with injected molded resin, the finished product may be affected by the substrate material, the ink used in design printing, selection of binder, printing conditions, printing order, drying method and conditions, selection of molded resin, mold design (type and position of the injection gates, number of gates), and the injection conditions, etc.
  • Preliminary testing under actual conditions is strongly recommended before a commercial run.
  • When using binders, we recommend "IMB-HF006 Binder" (various substrates) or "IMB-HF009 Binder" (PC substrates) which are halogen-free.
  • Ink shelf life: 24 months from production date, unopened.

  • 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.

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.

Is there any information related to high transparency inks?

The MIX-HF ink series offers “High transparency” and “excellent leveling property” more than ever before. The haze value in MIX-HF000 medium (*) is as low as 0.6. In addition to MIX-HF, there are other inks with high transparency such as TOC-HF. Please select the ink that best suits your application.

(*) Haze value: Haze value is the ratio of diffuse light transmission to total light transmission when irradiated with visible light. The smaller the haze value, the better the transparency.
Haze value(%)=Td/Tt x 100 (Td:Diffusive transmittance, Tt: Total transmittance)
