MacDermid Enthone M-Series Permanent Marking Inks

M-Series inks are permanent, two component, epoxy-based marking inks.
They may be used with a selection of catalysts which cure at elevated and/or room
temperatures. When properly applied and cured, M-Series inks have excellent
adhesion to glass, metal and  thermosetting plastics. They have  excellent 
chemical  and  thermal resistance properties.

Available Sizes: Bi-Paks (1/3 oz.), 6 Ounce Kits, 1 Quart Kits

Methods of Application


Machine Marking

Minimum pressure is recommended for transfer-paid or flat-bed printers. Adjust rollers to 0.5 mils clearance prior

to the addition of ink. Increase the depth of the ink on the roll feeds until the ink is transferred. Additions of

AD2003 retarder may be used during the print run.

Hand Stamping

Use a brayer to roll out a thin film of ink onto a glass or metal plate. Transfer the ink from palate to the part with a

rubber, neoprene, or urethane stamp. Minimum pressure provides a shark image definition. Disposable stamp

pads made of finely textured polyurethane foam or foam rubber may also be used. Because the ink begins to

solidify at the end of its pot life, stamp pads cannot be reused.

Screen Printing

Monofilament polyester fabrics with a mesh count of 180-330 may be used. Mesh tension should be to the fabric

manufacturer’s recommendations. Stencils may be applied by, indirect, or direct/indirect methods. Squeegee

material should 70-80 durometer, sharp and free of nicks. Squeegee durometer, pressure, angle, and print speed

should be adjusted according to overall printing parameters to ensure high quality print definition.


Following the induction period, think with AD2002 or a blend of 80% PM glycol ether and 20% methyl isobutyl

ketone at 25-40% by volume, depending on the air pressure and orifice of spray unit. Thinner additions will extend

the pot life considerably
