UV BUL Screen Ink (UV Curable Ink for Blu-ray Disc)

Teikoku UV BUL ink is UV curable screen printing ink designed for label printing of Blu-ray Disc, the next generation of optical discs. It has superior adhesion to hard to adhere surfaces like metal treated layer with extremely low shrinkage and small tilting angle. It’s hard surface finish provides very good resistance.

Label printing of Blu-ray Disc on metal treated layer or inorganic layer printing surface.

♦ Superior adhesion to metal treated layer, or inorganic layer.
♦ Superior suitability for printing on Blu-ray Disc with extremely low shrinkage.
♦ Suitability for high speed printing, depending on CD printer.
♦ Hard surface finish of ink layer provides superior abrasion and alcohol resistance.
♦ Low odor, Low skin irritation.

♦ Thinning is not required for standard applications.
♦ Use RE-804 Reducer up to 5% when required.
♦ "Teikoku Screen Cleaner N" is recommended to clean the stencil. Do not use Reducer for cleaning of stencil.

♦ Stir well before every use.
♦ 350 mesh monofilament stencil is recommended.
♦ Printing mesh may change depending on the color matching ink (metallic or pearl etc.).
♦ Coverage with 350 meshes will be 50-60 m²/kg.

♦ Curability and adhesion of UV BUL ink may be affected by:
1) Lower ink layer’s color, 2) Ink layer, 3) Type, grade, color of substrate, 4) Multi-layer printing,
5) Type of UV lamp and exposure conditions, 6) Treatment degree of substrate.
♦ 1.4 seconds Tact speed, 140W/cm are our standards with CD printing machine.
♦ Accumulated energy is about 430 mJ/cm².Peak Power is 430 mW/cm².

♦ UV Thixotropic agent: Use to increase the viscosity by adding up to 2%.

♦ Wide range of color matching (including metallic and pearl colors) is possible.

Ink is stabile for 6 months from shipping.
Adhesion testing must be done at your site with actual substrate. Slight change in substrate, process and printing might affect the results.

Not Flammable.
Use safety gloves and eyeglasses to protect skin and eyes. If the ink or coating contacts the skin, wash with plenty of water and soap. In case of contact with the eyes, wash with plenty of water and consult with a doctor. Containers should be tightly closed immediately after use, and stored in a dark and cool place.
MSDS is available. Please ask for a copy, and read it carefully before handling materials. Please follow the instructions.
