UV MARKING OR LEGEND INK
USM-U2 W169B/UV-3002 SK30, USM-U2 C179/UV-3003 SK26 series marking and legend ink are suitable on various PCB for either soldering side or component side. The special 100% solid content and solvent-free composition of these one part inks enable rapid and total curing via the exposure to low energy UV ray. They are adhesive to the surface of any solder resist inks or laminates and the three-dimensional character shows obvious effect when use as enhanced solder resist ink between adjacent pads.
Compared with W169B and C179, SK30 and SK26 are competition in price and lower energy.
Characteristics of USM-U2 W169B/UV-3002 SK30 , USM-U2 C179/UV-3003 SK26.
☆Excellent printing ability that is able to print marks and legends clearly Good adhesion to the laminate and the solder resist ink without separation.
☆Good resistance to molten solder with no discoloring, peeling occurred during the process of wave soldering, roller tinning or hot air leveling etc.
☆Excellent resistance to chemicals that is able to withstand the attack of solvent, fluxes and electroplating chemical.
☆Remarkable mechanical properties like hardness adhesion, wear resistance etc.
☆Easy removal of ink thus less the pollution.
