| DM-OC-6050S | Blue thermoset polymer overcoat for screen printing protective layers, solder dams, and marking over thick film resistor and conductor circuits. The blue colour provides visual contrast for inspection and marking, and the paste is solderable for downstream assembly. Prints on ceramic, stainless steel, and PCB; cures at 150–250 °C. Other colours available on request. | Heaters, PCB | Blue, Solderable | Screen | Ceramic, PCB, Steel | 150 - 250 |  | heaters pcb | screen | ceramic pcb steel |
| DM-OC-6060S | Semi-translucent thermoset epoxy overcoat for screen printing protective layers over thick film resistor and conductor circuits. The semi-translucent finish is formulated for laser marking, allowing permanent part identification through the coating, and the paste is solderable for assembly. Prints on ceramic, stainless steel, aluminium, and PCB; cures at 150 °C. | PCB | Semi-translucent for use with laser marking, Solderable | Screen | Ceramic, PCB | 150 | | pcb | screen | ceramic pcb |
| DM-OC-6051S | White thermoset polymer overcoat for screen printing protective layers, solder dams, and marking over thick film resistor and conductor circuits. The white colour gives high-contrast legend and marking legibility, and the paste is solderable for downstream assembly. Prints on ceramic, FR4, stainless steel, and PCB; cures at 150–250 °C

The overcoat layers can be either screen or inkjet printed and UV or thermally cured. Our overcoat inks and pastes, which are epoxy based, offer exceptional levels of mechanical robustness ensuring protection of the underlying circuitry against handling damage.
Due to their exceptional mechanical properties, the overcoat inks can be readily overprinted with conductive materials. These materials offer excellent chemical resistance.
We provide overcoat inks and pastes to a global customer base, offering a flexible delivery service from low volume samples to high volume to meet our customers’ production needs. We can rapidly tailor formulations for specific customer requirements.
Benefits of our overcoat paste systems:
- Excellent stability >6 months
- High-throughput printing performance
- Excellent screen life > 8 hours for screen printing
- Excellent adhesion to a broad range of substrates including FR4, ITO-glass, polyimide and metals
- Excellent surface hardness >8H
- Chemical resistance
- High area coverage enabling reduced paste consumption
- Screen printing compatibility – flat bed and rotary
- Low temperature curing – use on flexible substrates
- No drying requirement
