Ink
RC PF 42 Series
Properties
Good flexibility, opacity and heat formability.
PREFAC
RC PF 42 SERIES forms flexible ink film with matt finish. RC PF is suitable for polycarbonate industrial meters which require post-print processing. RC PF is also recommendable for membrane switches of treated PET films.
APPLICATIONS
Polycarbonate, treated PET films, PVC stickers, rigid vinyl, AS, ABS, acryl(injections), paper
CHARACTERISTICS
- Flat and matt finish. Excellent flexibility.
- High density and high opacity.
- Adhesion and over-printability are good.
- Reproducibility of fine patterns is good.
- Stable on the screen.
HOW TO USE
- Ink is supplied in ready-to-use condition. Stir well before use. Matt finish can be obtained after UV curing.
- Add 42-00 REDUCER up to 10% to lower viscosity. Viscosity is lowered without spoiling matt finish.
- The grade of matt finish changes depending on curing conditions or environmental temperature although it does not change after curing. To up-grade matt finish, take more time for levelling.
- Standard curing conditions(The conditions depend on the substrates.)

PRECAUTIONS
- Skin irritation(P.I.I.) of each color is low(under 2.0). However, it is advised to avoid skin contact. In case of skin contact, please wash with soap and water immediately.
- Store the ink in a cool and dark place. Stir occasionally to keep stability when the ink is stored for a long time.
- Stir well before use as de-foamer might be separated.
- Standard thickness of colored ink film is 10-12 microns. If the thickness exceeds 15 microns, insufficient curing may cause poor adhesion.
- Please refer to MSDS before use.
- Be sure to do trial print before commercial run to confirm that the product fits the purposes.
