Product overview

IMB-HF005 PP Binder Ink provides a binder function that makes PP resin adhere to a design printed sheet when manufacturing decorative molded products using PP resin in Film Insert Molding(FIM).

Application

  • Adhesive layer for FIM(film insert molding)
  • Resin adaptive to injection molding: PP resin

Features, Function

  • Adhesive layer between a design printed sheet on treated PP with 2 pack curable ink and injection molding resin.
  • Applicable to film insert molding of PP resin, which is a difficult material to adhere to.
  • As screen printing is possible, pattern coating can be applied to only necessary areas.
  • According to the raw material and product specifications, our molding inks can be used. For treated PP, INQ-HF ink is recommended.

Substrate

  • Treated PP
  • Please print INQ-HF000 MEDIUM as an under layer when printing on the transparent area of PC and treated PET substrate.

Dilution

  • Dilution is not required.
  • If dilution is required due to printing conditions, use SCREEN CLEANER PP within 5%
  • *Stir well before use. It may be jelly after opening the container, but it will return to liquid when stirred.
  • *Do not use other solvents as they may cause contamination of halogen compounds and may adversely affect curing, adhesion, stencil stability, or other properties

Recommended cleaner

  • SCREEN CLEANER PP

Mesh

  • T 150 Mesh An ink layer thickness of 5 to 10μm is optimal.

Drying

  • Tack free 80℃ 10 min(30 min for 60℃)
  • Final drying
    Please dry under the final drying conditions of under layer ink,
    (INQ-HF:80℃ 60 min)

Caution

  • Do not use solvents 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 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.
  • Binder cannot be used by mixing with screen ink.
  • When printing a binder, if the underlayer ink is excessively dry, peeling strength will be reduced. Be sure to print continuously up to the binder and conduct final drying.
  • Residual solvent in the ink layer may cause poor adhesion to the molding resin. Be sure to conduct heat drying including drying and curing of design printing inks.
  • Use our G-002 SOLVENT for cleaning stencil.
  • Checking before commercialization: Adhesion and resistance properties may change due to differences in substrates, processes, printing and drying conditions. Be sure to check the adhesiveness and resistance properties before mass production printing
  • Ink shelf life: 12 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 a binder?

It is a binding layer, which enhances the binding between the injected resin and the inserted print matter, principally printed with 2 pots of curing ink.

We recommend reading the following reports:
IMB-HF006 Binder (Halogen Free, Environmentally Friendly Binder for IMD/FIM)

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.
