UV MET Screen Ink (UV Curable Ink for Metals)

Teikoku UV MET is a UV-curable screen printing ink for stainless steel, aluminum and other metals.

Applications & Substrates

♦ Aluminum, Stainless Steel, Steel, Zinc, Ceramics, and Plated Metals.

Special Features

♦ Good adhesion and high gloss finish
♦ Hard surface and superior abrasion resistance
♦ Superior solvent, acid and alkali resistance
♦ Good stability on stencil
♦ Low odor, little skin irritation

Thinning & Cleaning

♦ Stir well before every use.
♦ Thinning is not required for standard applications. However, thinning with RE-805 up to 5% improves the printability when printing at high-speed.
" Do not use thinner to clean the stencil. "Screen Cleaner N" is recommended to clean the stencil.

Printing

♦ 300-380 mesh monofilament screen is recommended. Coverage is about 60-90 m2 /kg. with 300 mesh.

Curing

♦ Curability and adhesion of UV MET 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.
♦ Two 80 w/cm metal halide lamps, 15cm lamp height, and 5 m/min. belt speed is considered standard. Accumulated energy is about 480 mJ/cm2 .
