Product Description

DM-OC-6050S is a thermoset polymer protective overcoat for use with Dycotec’s range of the thick film resistor and conductor pastes for use on ceramic, stainless steel and PCB substrates. The paste acts as a protective coating, solder-dams and can also be used as a marking ink. The standard product is blue in colour but other colour are available on request.

Product Benefits

• Excellent printability, enabling good edge definition for circuits needing high resolution dams between solder pads
• Wide tolerance on thermal processing temperatures (150-250oC)
• Good solvent resistance
• Single part system
• Compatible with SAC solderpaste types

Paste Preparation

Bring paste up to room temperature (20-25°C) by storing in the print area at least 2 hours prior to printing. Before use, the paste should be thoroughly but gently stirred with a spatula to avoid incorporation of air bubbles.
