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.

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.

表格
| Item | Ceres Screen‑Printing Silver Conductive Ink | Generic domestic low‑cost silver ink | Premium imported silver paste |
|---|---|---|---|
| Filler & electrical performance | Well‑dispersed flake silver powder, ≤25mΩ/□ @12μm | Poor silver‑powder quality, large batch‑to‑batch resistance fluctuation | High‑purity flake silver powder, ultra‑low resistance |
| Printing property | Good screen‑print performance 200‑300 mesh, low clogging risk | Poor thixotropy, bleeding & edge‑spreading risk | Excellent printing behavior |
| Curing window | 120‑130℃, 10‑15min, PET‑friendly | Narrow curing window, resistance spikes with temp deviation | Wide curing window, high price |
| Package | 500g sample can +1kg stock can | Mostly 1kg only, no small sample cans | Large minimum order, long lead‑time |
| Lead‑time | 3‑day stock delivery | Unstable stock | 3‑6 weeks lead‑time |
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.”
