INQ-HF Screen Ink (Halogen-free, isophoron-free, environmentally friendly, 2pack Ink for IMD)

INQ-HF Ink Series is environmentally friendly 2 pack ink for IMD/FIM with no intentional use of Halogen compounds (Bromine (Br), Chlorine (Cl)) and its Benzene, Toluene, Xylene, Isophorone free content. Its ink layer has superior flexibility. When Film Insert Molding is done, INQ-HF provides superior heat resistance and adhesion, especially good adhesion to TPU.

Pattern printing on TPU, treated PET film and PC sheet for film insert molding.

Suitable for IMD/FIM applications with PMMA (Acrylic), AS, ABS, PC/ABS resins in combination with IMB binder.

• Halogen compounds, Bromine(Br), Chlorine(Cl) are not intentionally used in raw materials.
• Two-pack ink that provides ink layer with excellent heat resistance.

Refrain from using solvents and catalysts other than specified ones as Halogen components may interfuse. Check halogen contents of squeegee rubber, emulsion, substrate and other equipments, before using as they may contain halogen components.

Since some substrates are required annealing (heat treatment), preliminary test with actual substrate is strongly recommended.

Stir ink in the container well before every use.

To adjust the viscosity, thin with 15-20% of F-003 Solvent. F-002 (fast dry), F-003 (standard), Z-705 (slow dry) may be used as well depending on printing conditions. Avoid using other solvents or excessive thinning as it might cause lack of adhesion to insert-molding resin.

• Catalyst Information

• Pot life at room temperature (25°C) is about 4-5 hours.  Do not use the expired ink as it may not perform as intended.
• Screen Cleaner N is recommended to clean the stencil.
• SM-40 Defoamer can be used 1-3% to avoid foaming or to improve leveling.

Monofilament T-200-270 mesh is suitable as a stencil.
Coverage of about 35 m2/kg can be expected with a T-250 mesh monofilament screen.

• Heated drying is necessary.  Tack-free drying is about 10 minutes at 80°C.  After printing IMB Binder, complete drying should be done for about 60 minutes at 90°C. 
• Drying speed varies depending on drying conditions such as room temperature, humidity, type of dryer, printed area, substrate, mesh of stencil, etc. Preliminary drying test at actual printing conditions is strongly recommended.

• Use of IMB Binder series is strongly recommended.
  • IMB-HF009 Binder is suitable for Teikoku’s Mirror Inks, PC resin, PMMA resin.
  • IMB-HF006 Binder is suitable for general injection molding resin such as ABS, PMMA or AS resins.   Please refer to the respective Product Information Sheet.
• Insert molding is a very sophisticated system in which many factors such as substrate, pattern printing inks, binder, printing conditions, sequence of printings, drying condition, pre-forming conditions, molding resin, molding conditions, design of the mold (type, position and number of the gate) and injection conditions will affect the quality of the finished products. 
• Preliminary test with actual conditions before commercial run is strongly recommended. Follow instructions and use all ink products responsibly.

Flammable.       UN Class: Not included.      UN No.: Not included

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 the 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 the instructions carefully.
