Mixing & Drying Guidelines

For optimal stability and performance, forced baking is highly recommended over air drying.

Standard Use (1K Mode)

Ink formulation 100 Parts
Thinner (Std / Slow-drying variants) 15 - 30 Parts
Drying Schedule (1K):
  • Air Dry (25°C): Touch dry 10-20 mins, Hard dry 24-48 hrs.
  • Baking (Recommended): 90-100°C for 10 mins.

High-Performance Use (2K Mode)

Ink formulation 100 Parts
Hardener (B-5 or B-11 Catalyst) 10 - 15 Parts
Thinner 15 - 30 Parts

⚠️ Pot Life Alert: Mixed 2K ink will gell and expire within 5 - 8 hours.

⚠️ Gloss Change: Adding hardener will slightly increase the ink's gloss level.

Drying Schedule (2K):
  • Air Dry (25°C): MUST dry for at least 48 hours.
  • Baking (Recommended): 60-70°C for 90 mins, OR 90-100°C for 30 mins.

Frequently Asked Questions (FAQ)

Quick technical reference regarding halogen compliance, mechanical embossing, and pot life.

Is this screen printing ink series strictly certified as halogen-free?
Yes, absolutely. This advanced chemical series is formulated strictly to fulfill rigid international green mandates. It is completely free of banned halogens (Chlorine and Bromine content are kept safely under 900ppm), making it fully cleared for multinational electronic components and export membrane switch overlays.
Will the printed ink layer crack or delamination during key tactile dome embossing?
No. The cured ink film features elite elongation elasticity and high flexibility mechanics. It is custom-engineered to survive extreme post-processing physical duress, allowing you to thermoform, die-cut, and punch tactile domes/keys repeatedly without any hair-line cracking or foil delamination.
When should I transition the ink from 1K mode to 2K mode with catalyst?
For standard label and decal printing on paper or standard PVC, 1K mode (ink + thinner) provides sufficient performance. However, if your graphic overlays face severe environment specs, high humidity exposure, or strict industrial solvent wipes, blending 10-15% B-5 or B-11 hardener (2K mode) will drastically optimize its interfacial anchorage and chemical resistance.
What screen mesh count parameters secure the best light-blocking effect?
To maintain razor-sharp edge parameters while locking in excellent backlighting block-out effects, we suggest utilizing mesh configurations up to 420 mesh/inch combined with a sharp 75° durometer squeegee. Avoid printing excessively thick barriers, as heavy ink films will block airflow drying paths.
