Ceres Security Ink Screen Printing Conduction Ink
Printing‑Method Compatibility
‑ Screen Printing: ✅ Only recommended. 200‑300 mesh screen, add
special thinner 3‑8%. ‑ Offset / Letterpress‑Flexo / Gravure: × Not
applicable.
Important: Thermal‑curing is mandatory. Air‑drying cannot form conductive
network and will cause high‑resistance failure.
Substrate Compatibility
‑ Paper: Coated art paper / high‑density card: Excellent; Loose
uncoated paper not recommended. ‑ Plastic: PET / PC / PVC: Good; PP
/ PE requires corona treatment ≥40‑42 dyn. ‑ PI polyimide:
Excellent for higher‑temperature curing.
Electrical Performance (@12μm dry film, 125℃ /12min cure)

Package Options
‑ 500g/can: For lab R&D & trial‑run samples ‑ 1kg/can: Standard
mass‑production package, 12 cans per carton Consume within 1 month once opened. Silver powder sedimentation is normal; stir thoroughly 5‑10min
before printing.
Storage & Shelf‑life
Store at 5‑25℃, cool, dry, dark warehouse, keep tightly sealed.
Avoid freezing and direct sunlight. Un‑opened shelf‑life: 6 months from production date. Discard if caking / irreversible gel occurs.
Security‑&‑Function Test Instruction
‑ Visual check: Silver‑grey metallic printed trace. Appearance cannot judge conductivity. ‑ Core electrical test: Measure sheet resistance with multimeter /
resistance tester. ‑ UV / IR / Magnetic: No native UV‑fluorescent,
IR or magnetic property. Over‑print other security inks for
multi‑level anti‑copysolution.
Application
RFID tag antenna, membrane‑switch electrode, flexible printed
circuit, electromagnetic shielding coating, resistive heating film;
composite anti‑cppy mark with electrical‑readout feature.
Not suitable for long‑term outdoor exposure without lamination
protection.

FAQ
- MOQ: 1 kg for stock; 500g sample can available upon request.
- Lead‑time: 3 working‑days for stock; 7‑12 working‑days for custom
modified grade.
- Customization: Custom low‑resistance silver grade / carbon‑based
conductive ink / low‑temperature‑curing formula available. Cannot
convert to offset / gravure formula for this base item.
- Shipping: DHL / TNT / UPS, air & sea freight available; MSDS
provided for chemical transport.
- Troubleshooting high‑resistance: Insufficient curing temp/time;
excessive thinner; too thin ink film; silver‑powder oxidation after
long‑time opening; porous substrate ink penetration. Always test
sample resistance before mass‑production.
- Do NOT air‑dry without oven heating; thermal curing is compulsory.
- Dilution: Only use manufacturer‑supplied special conductive‑ink
thinner, do NOT add water.

Customer Cases & Testimonials
‑ Case 1: Domestic printed‑electronics factory, used for PET
membrane‑switch electrode printing, monthly purchase 60‑100 kg,
stable key‑contact performance. ‑ Case 2: Southeast‑Asia RFID tag
printer, screen‑printed paper‑based RFID antenna as alternative for
etched copper‑foil, repeat bulk‑orders.
“Good printability for screen‑printing, stable sheet resistance
after proper thermal‑curing, works well for membrane‑switch
electrodes.” “500g sample cans are convenient for lab trial‑run; silver‑powder
sediment recovers well after thorough stirring.”
