Enthone 50-Series Legend Inks are permanent, two component, epoxy-based screen printing inks.
They may be used with a selection of catalysts which cure at  elevated and/or room temperatures.
When properly applied and  cured, Cat-L-Inks have excellent adhesion to photoimageable, thermal
and UV solder masks, glass, metal and  plastic. They have excellent chemical and thermal resistance  
properties.  50-Series Cat-L-Inks are used in the  electronic, aerospace,  automotive,  appliance  and
decorative container industries. Uses include the permanent  marking of circuit  boards, semiconductor
components, connectors, dials,  nameplates, edge-lit panels, chassis,  glass and thermoplastics.

Monofilament polyester or metallized polyester fabrics with a mesh count from 180 to 350 are recommended.

Equivalent stainless steel fabrics may also be used. Mesh tension should be to fabric manufacturer’s



Squeegees should be between 60-80 durometer, sharp and free of nicks. Squeegee durometer, pressure, angle

and print speed should be adjusted according to the overall printing parameters to ensure consistent print

definition and ink film thickness.


Any lacquer resistant Direct, Indirect, Direct/Indirect or Capillary Stencil system.


If thinning is required, add small amounts of AD2001 or butyl cellosolve acetate. Additions should be made

after the induction period.Thinner additions extend the pot life.


Small amounts of AD2003 or carbitol acetate are recommended. Additions should only be made after the

induction period has been observed.


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

ketone at 25-50% by volume, depending on air pressure and orifice of spray unit. Thinner additions

will extend the pot life considerably.


Enthone SC1710 screen cleaner, AD2003 or any lacquer wash will effectively clean screens and

equipment before the ink cures.
