ITW Trans Tech: Pad Printing Ink: Type UVHC

INSTRUCTIONS:

NOTE: Read Material Safety Data Sheet (MSDS) Prior To Use

Ink Type UVHC is supplied in paste form. This ink is recommended for open ink well and sealed cup pad printers.

PAD PRINTING:
Recommended cliché depth for pad printing is 20 to 26 microns, depending on type of cliché. The ink can be applied single or double hit.

GLOSS LEVEL:
Ink type UVHC is available in a matte and gloss finish. The matte and gloss type inks can be mixed for a custom gloss level.

Under normal conditions, the ink should be adjusted with thinner. The ink is UV light-reactive. Avoid long term direct exposure to light when using. Yellow plexiglas machine guarding is advised. Recommended room temperature 70 – 78 degrees F. Recommended room humidity 30 – 50 %

ADDITIVES: (See Additives Chart for more listings)

Thinners:
THINNER C for most applications (10 TO 15 % by weight)
THINNER B (10 To 15 % by weight) Slower evaporating than "C"

Retarder:
TPD RETARDER (1 To 3 % by weight)

DRYING & CURING: (See Ink Drying & Curing Times Chart )

Ink TYPE UVHC remains tacky until curing takes place.

PREHEAT: (Optional) Ink performance may be increased with IR treatment immediately before UV light curing, typically 140 – 170 Degrees F for at least 35 seconds.

UV LIGHT CURING: Ink TYPE UVHC only cures under UV radiation of suitable wavelength and intensity. Curing parameters depend on layer thickness, and substrate.

UV EXPOSURE: Expose to a medium pressure, Mercury vapor type lamp operating at a minimum of 200W per inch imput power. Curing energy should be between 1000 and 2000 mJ/cm² . After curing, the ink is dry to the touch that can be handled aggressively without damage. Maximum chemical and abrasion resistance will be seen after a period of 24 hours.

COLORS: (See Color Availability Chart )
Ink Type UVHC is is available in:

INK-UVHC #70 CLEAR GLOSS 1 LITER
INK-UVHC #70 CLEAR MATT 1 LITER
