RC CDV-SGX SERIES

INTRODUCTION

RC CDV-SGX SERIES is designed for label-printing on UV protective coating of CDs and CD-Rs. Ink film is resistant to abrasion. Adhesion and curing are excellent.
Coverage of RC CDV-SGX SERIES is much improved compared with CDV-S SERIES.
10 WHITE has been added to this series. 10WHITE is superior in opacity, coverage, curing, and adhesion.

APPLICATIONS

Printing on CDs and CD-Rs.

CHARACTERISTICS

• Ink hardly drops off the screen by rheology control. Suitable for high-speed printing.
• Good resistance to chemicals such as acid or alkali.
• Ink film is gloss and resistant to abrasion.
• Skin irritation(P.I.I.) is low and it is easy to handle.
• RC SGX SERIES is made in Japan under strict quanlity control.

HOW TO USE

1. Ink is supplied in ready-to-use condition. Add CLEAR to adjust density.
   Add REDUCER(reactive type) to adjust viscosity.
2. CDV-SGX SERIES is not compatible with other series of UV inks.
3. Standard curing conditions(Conditions depend on colors.):
   Metal halide lamp 120W/cm,
   Integral light : approx. 300mJ/cm²,
   350nm peak power : 300mW/cm²
4. Mesh : 300-420 meshes

COLOR RANGE

• Standard colors: 17 color shades
• Halftone colors: 4 color shades (2 type, gloss finish and matt finish, are available.)
• Gold(clear type): 8 color shades
• Silver(clear type): 7 color shades

COVERAGE

6,000-7,000 discs/kg (polyester 350 meshes)

PRECAUTIONS

1. Both matt and gloss finish are available for halftone colors.
2. Use 01 WHITE when matching colors.
3. If spin-coating is cured too hard, adhesion will be poor.
4. Although skin irritation is low, avoid direct contact with skin. When the ink contacts with skin, wash immediately with soap and water.
5. Store the ink in a cool and dark place. Ink gels or increases its viscosity when left in hot place (>30°C)(>86°F).
6. Stir well before use.
7. Please refer to MSDS before use.
8. Be sure to do trial print before commercial run to confirm that the product fits the purposes.
