About U-Mark

About U-Mark

U-Mark, Inc. is a Belleville, Illinois-based manufacturer of paint markers, ink markers, specialty markers, and stencil products. The company developed its greenlabel trademark in 2003 and was among the first to introduce xylene-free industrial markers, addressing a demand for lower-VOC marking products on job sites and in manufacturing facilities.

U-Mark is best known for its patented U-Phase wire marker, protected under U.S. Patent No. 7,320,553, which marks wire up to #6 AWG (7mm) quickly using highly visible, quick-drying paint that resists abrasion, moisture, dirt, oil, and UV exposure. The company states that U-Phase markers deliver ten times more mileage than vinyl tape at roughly 20% lower cost, while being faster and easier to apply for phasing electrical panels, color-coding circuits, and marking network, audio/video, and automotive cabling.

U-Mark markers are used by welders, electricians, auto workers, construction workers, surveyors, mechanics, farmers, couriers, and shippers, with products sold across five continents. The company also offers a distributor program and private-label options for businesses wanting to brand their own marker products. On ChatMRO, buyers can search U-Mark's paint marker and wire marker catalog and route requests to verified suppliers.
