HF-PC Electroplating Screen Printing Ink

1. Обзор и области применения

The HF-PC Series is an advanced 2-component, reactive screen printing ink explicitly formulated for printing over delicate electroplated surfaces. It is characterized by its high opacity, smooth satin finish, and premium adhesion.

Anti-Mirror-Burn Technology: Its most critical feature is its non-corrosive chemical structure. It prevents "mirror burn"—meaning it will not etch, corrode, or dull the sensitive electroplated metal layer, fully preserving the original mirror effect.

Подходящие основания: Electroplated raw PC (Polycarbonate) sheets, PVC sheets, and Acrylic (PMMA) sheets.

2. Environmental Compliance & Colors

• Halogen-Free (HF): Fully compliant with strict Halogen-Free industrial standards.
• RoHS & Low Odor: Meets EU RoHS 6 standards. Formulated without benzene or heavy environmental-burden solvents, providing a friendly, low-odor work environment.
• Available Colors: X-102 Extra White, X-702 Extra Black.

3. Mixing Instructions & Ratios

Срок годности: Once the B-5 Hardener is added, cross-linking begins. At standard room temperature (25°C), the usable pot life is 4 to 6 hours. Do not use the ink beyond this timeframe, as adhesion and printability will rapidly deteriorate.

4. Strict Printing & Curing Workflow

Because electroplated surfaces are highly sensitive, standard air-drying is strictly prohibited. Operators must adhere to the following forced-baking workflow to ensure adhesion and prevent corrosion:

• Step 2: Touch Dry (IR Tunnel): Выпекать при температуре 60°C for 8 - 10 minutes until touch-dry.
• Step 3: Hard Dry (Oven): Transfer to an oven and bake at 60°C - 70°C for 30 - 60 minutes. This thoroughly flashes off all residual solvents. (Note: If overprinting a second layer, repeat steps 1 through 3).
• Step 4: Final Cross-Linking: After baking is complete, let the printed pieces sit at room temperature for 24 to 48 hours. This allows the hardener to fully cross-link and achieve maximum bonding strength.
