Enthone M-Series Inks – Formulated for Transfer Marking

Permanent, two component, epoxy-based transfer marking inks with a gloss finish. Recommended for Marking, Roll-to-Roll Transfer Printing, Stamping. Enthone M-Series Inks are designed for use with a selection of catalysts (see below) which cure at elevated and/or room temperatures. When properly applied and cured, these inks have excellent adhesion to glass, metal, and thermosetting plastics. These inks also have high chemical and thermal resistance properties. Enthone M-Series marking inks are used in the electronic, aerospace, automotive, appliance, and decorative packaging industries. Uses include the permanent marking of semiconductor components, printed circuit boards, connectors, dials, nameplates, panels, chassis, glass, and thermoplastics. Shelf life is 3 years from date of manufacture.

Enthone 50-Series Cat L Inks – Designed for Screen Printing

Permanent, two component, epoxy-based screen-printing inks designed for use with a selection of catalysts which cure at elevated and/or room temperatures. When properly applied and cured, Enthone 50 Series Cat L Inks have excellent adhesion to solder masks, glass, metal and plastic. They have
excellent chemical and thermal resistance properties. These inks are used in the electronics, aerospace, automotive, appliance and decorative container industries. Some uses include the permanent marking of circuit boards, semiconductor components, connectors, dials, nameplates, edge-lit panels, chassis,
glass, and thermoplastics. 50-Series inks have a gloss finish, aside from 50-110RX White, 50-710R Black (low elec. Resistance), 50-770R Black (high elec. Resistance), and 50-810R Clear. Shelf life is 3 years from date of manufacture.

Enthone M-Series and 50-Series Catalysts

The catalyst is the second component in the two-part “set” that consists of one ink and one catalyst. These catalysts can be used for both M-Series and 50-Series inks. Please note these items are purchased
individually, so you can order whatever number of ink and/or catalyst that is needed. Pricing on the catalyst is offered at a lower “set” price when purchased together with an ink compared to catalysts that
are purchased individually or as extras on an order. Shelf life is 2 years form date of manufacture. Some impacts your catalyst choice can make:
– Allows average ink pot life from 1 to 24 hours.
– Determines post-cured material conditions such as conductivity, electrical resistance, and outgassing levels
– Can affect resistance to chemicals, moisture, and anti-yellowing
