CARPINTERIA, Calif.—NuSil Technology L.L.C. has launched a series of heat-cure colored inks called MED-6613-X.
The newly released colors—red, white, green, bright blue and dark blue—expand the company's color palette, NuSil said.
NuSil's inks feature a long work time and non-volatile content of about 60 percent, the company said. Depending on the ink color, viscosities range from 800 to 3000 cP and can be decreased through dilution via compatible solvent.
These two-part, addition-cure inks can be used in pad-printing and silk-screening processes for marking or coloring silicone rubber parts, such as catheters, NuSil said. The company said because the cure is accelerated with heat, these inks are suitable for applications requiring a rapid cure time.
The suggested cure schedule is five minutes at 150°C.
This line of silicone inks was a collaborative effort between NuSil Technology for silicone development and C.I. Medical Inc. for application feedback.
