Color Agents

Description
Color Agent is a one part, air-drying, semi-paste ink commonly used for printing on hard surfaces, including circuit board base materials. Color Agent can be applied directly to circuit board surfaces prior to overcoating. When applied directly to a circuit board surface apply a thin coating and cure for 24 hours at room temperature or 4 hours @ 65°C (150°F).

Color Agent can be used to tint the color of 115-3302 Circuit Bond epoxy used for solder mask repair or circuit base board repair. For information on 115-3302 Circuit Bond go to: www.circuitmedic.com/parts/115-3302.

Color Agent is supplied in 1 oz. (29 ml) collapsible metal tubes.
