The HF HSD series is a family of two-part reaction type inks. They can be widely applied to various materials, and offer excellent printability. Having a flexible ink layer, they can also be applied in in-mold decoration. This series of inks is halogen-free and environment-friendly.
Ink type | Polyacrylate-based two-part isocyanate hardener-type. |
Usage | Excellent adhesion on various materials, suitable for materials such as processed PP, coated surfaces, ABS, PMMA, hard-coated PMMA, PC, processed PET, and aluminium. |
Features | • Gloss Finish • Widely applicable, demonstrates excellent adhesion to most substrates. • Excellent moisture and solvent resistance. • Halogen-free |
Diluent | • Standard solvent: T-926 • Slow-dry solvent: T-927 • Retarder: T-980 |
Mixing ratio | • Ink: D-Hardener = 100:10) • Gel phenomena may occur after 6-8 hours of usage at room temperature after mixing, leading to reduced physical performance. |
Washup | T-15/T-31 |
Screen | 200-300 mesh/inch polyester or nylon screens recommended. |
Drying time | • Sets to touch-dry in 40 minutes at 25°C. • Hard-dries in 1 week (air-drying) or 30 minutes at 80°C+2 days air-drying. • When applied to metal substrates, thermal curing for 20 minutes at 120-150°C is required for optimal results. |
Notes | • When used on electroplated film, dilute with solutions T-900 or T-910 to prevent solvent attacks to the substrate. (Verification is advised based on substrate differences) • D-Hardener is extremely sensitive to moisture. Use as soon as possible after opening. • Bubbles and/ or pin-holes may form based on printing conditions. Add 1-2% (by weight) of CARE 13 as needed. • Add 3-5% of CARE 73 to enhance adhesion to glass and resistance to boiling and alcohol. |
Material | Polycarbonate plate |
Ink | HF HSD 120, 710 |
Curing | 30 minutes in 60°C, followed by 1 day in room temperature. |
