IPX Screen Ink (Low-odor, Environmentally-friendly, Two-pack screen ink for IMD/FIM )

IPX is a low odor, environment and human friendly screen ink that is free of benzene, toluene, xylene, and isophorone. Suitable for IMD/FIM with superior heat resistance and good adhesion to treated PET film and Polycarbonate (PC) sheet. Suitable for fine printing of nameplates and membrane switches.

Applications & Substrates

♦ Pattern printing on treated PET film and PC sheet for IMD/FIM
♦ Suitable for Injection Molding Resins: Acrylic, AS, ABS, PC/ABS, PC

Special Features

♦ Two-pack ink with superior heat resistance
♦ Superior flexibility for post-forming treatments: Embossing, pressing and squeezing
♦ Good resistance needed for IMD/FIM with curability at 90°C
♦ Wide range of colors with excellent heat and weather resistance

Thinning, Stirring, Cleaning

♦ Stir well before every use.
♦ Use F-003 (Standard) thinner with 10-15% dilution. F-002 (fast dry) and Z-705 (slow dry) thinners are also available.
♦ Avoid excessive thinning and avoid using other solvents as this may decrease printability and cause lack of adhesion between the ink layer and the injection resin during IMD/FIM.
Screen Cleaner N is recommended to clean the stencil.

Mixing

♦ Use 240 Catalyst with 10 wt. % dilution just before printing and mix well.
♦ For a soft ink layer, use 220 Catalyst with 15 wt. % dilution and mix well. 200 and 106 Catalysts are also available. See table for catalysts and dilution ratios.

♦ Pot life is about 4-5 hours at room temperature (25°C). Do not use the expired ink as it may degrade the performance of the product.
♦ SM-40 Defoamer can be used 1-3% to improve leveling or to avoid foaming

Printing

♦ T-200-270 Monofilament mesh is recommended. Coverage is 35 m 2 /kg at T-250.

Drying

Heated drying is required ; tack-free time is about 10 minutes at 80°C with a box dryer.
♦ Final drying should be done for 60 minutes at 90°C after printing IMB Binder.
♦ Drying time varies according to drying conditions such as room temperature, humidity, type of dryer, printed area, mesh of stencil, substrate, etc. Preliminary testing under actual conditions is strongly recommended before a commercial run.

Caution

  Adhesion to injection molding resin varies according to types and grades of resin.
In various forming processes such as vacuum forming, pneumatic forming and mold forming, or in the Film Insert Molding process (in which injected resin is integrated with the substrate), the finished product may be affected by any of the following: the type of substrate, the ink used in pattern printing, the printing conditions, the printing order, the drying method, the forming resin, the mold (type, position of the mold and shape, number of gates), the injection conditions, etc. Preliminary testing under actual conditions is strongly recommended before a commercial run.
  IMB Binder series is strongly recommende d to improve the adhesion of the ink layer to the injection molding resin . IMB-009 Binder is recommended for Teikoku's Mirror Inks, while IMB-003 Binder is suitable for general injection molding resins such as ABS or PMMA. Please refer to the related Product Information Sheet.

Safety and Handling

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