EG Screen Ink (Gloss Ink for PET Nameplate)

Superior adhesion to various Polyester Films

Substrate& Application

♦ Suitable for membrane switch applications with treated or untreated polyester films.
♦ Suitable for fine printing for all kinds of stickers.

Special Features

♦ Superior gloss finish with good printability
♦ Superior light and weather resistant colors are available
♦ Ink layer is flexible and shows superior adhesion
♦ Ink layer's physicality can be improved by using catalyst

Thinning & Cleaning

♦ Stir well before every use.
♦ Use H-002 (Standard) thinner with 5-20% dilution. H-001 (Fast Dry), H-003 (Slow Dry) or H-004 (Extra Slow Dry) thinners are also available.
♦ Avoid using other solvents as it may cause blocking and lack of adhesion.
Screen Cleaner N or H-002 thinner is recommended to clean the stencil.

Catalyst

♦ Use 96 Catalyst or 101 Catalyst to improve the adhesion.
♦ 96 Catalyst: Add 5% (6% for Medium ink) and mix well.
♦ 101 Catalyst: Add 7% (8% for Medium) to improve the transparency.
♦ Drying time for both catalysts is about 15 minutes at 80°C.

Printing

♦ 200-270 monofilament mesh is recommended. Coverage is 30-40 m 2 /kg at 225 mesh.

Drying & Curing

♦ Touch drying time at room temperature is about 7-10 minutes.
♦ Complete tack free time printed ink (conditions: 20% dilution with H-002, T-250 mesh). is 30~40 minutes eventhough it may change according to size of printed area, room temperature & humidity or printing mesh.
♦ Heated drying is recommended for 30-40 minutes at 60°C or 20-30 minutes at 80°C.

Additives

♦ Use leveling agent 1~2% to improve the leveling
♦ To avoid foaming if transparency is not needed use SM-100A Defoamer 1~2%, if transparency is needed use SM-40 Defoamer 1~2%.

Caution

Adhesion testing must be done at your site with actual substrate before commercial run. There may be a difference between substrates from different manufacturers, even different batches. Migrated plasticizers and additives may cause lack of adhesion. Alcohol treatment may be effective to solve the adhesion problem.
