RC OP 43 SERIES (OVER COAT CLEAR)

PREFACE

RC OP 43 SERIES OVER COAT CLEAR(O.C.C)is designed for over-coating on offset and gravure prints.
HG O.C.C has excellent curing and adhesion. Low-cost version, NOP O.C.C and LOP O.C.C are also available.

APPLICATIONS

Paper, over coating on offset prints and gravure prints, laminated materials, laminated matt PP materials

CHARACTERISTICS

• Suitable for high-speed printing like cylinder press.
• Fast cure. Blocking resistance is good when the printed matters are stacked.
• Adhesion to offset prints and matt PP materials is good.
• Cured ink film has good levelling and abrasion resistance as well as high gloss.
• No harmful materials such as heavy metal and N-Vinyl Pyrrolidone are contained.

HOW TO USE

1. Ink is supplied in ready-to-use condition. Stir well before use.
2. Add 43-00 REDUCER up to 10% if it is necessary to lower viscosity.
3. Standard curing conditions :
   Mesh count : 350
   Sol thickness(microns) : 10
   Conveyor speed(m/min) : 20
   Integral light(mJ/cm²) : 120
   Ink film thickness(microns) : 10-12

• Lamp power : One metal halide lamp 120W/cm
• Distance from focus : 10 cm
• Cooling : Water cooling or air coolin

COVERAGE

PRECAUTIONS

1. Blocking resistance is effected by the gloss of the paper on which the ink is printed.
   Blocking may happen to thickly-printed ink when the substrate is glossy paper.
2. Please refer to the literature, "UV INK" for general precautions.
3. Please refer to MSDS before use.
4. Be sure to do trial print before commercial run to confirm that the product fits the purposes.
