Colorful Durability - PLT4G Ink
|
CHARACTERISITICS: PLT4G ink is a two-component series ink that is dust dry in about 20 minutes. Remarkable for its good coverage. This ink has a semi-gloss to gloss finish depending on the printing surface. After proper curing, products printed with PLT4G may be silvered using common silver-plating methods.
APPLICATIONS: Particularly suited for printing on glass, and ceramics such as glass panes, glass bottles, ornamental glasses, ceramic tiles, ferrous and non-ferrous metals. Good results are also obtained on thermo-setting materials in general.
RESISTANCE: PLT4G has an excellence resistance to many organic solvents, and chemical products. To increase the water and weather resistance, we recommend to heat the ink using an oven at 140 degrees C for 30-60 minutes.
FLASH POINT: Above 48 degrees C.
PREPARATION: As a two-component ink series, PLT4G must be mixed with hardener and thinner before use. Mix in a ratio of 20 parts ink to 1 part hardener. It is recommended that the mixed ink be allowed to rest for 15-20 minutes before printing. Thin and mix well the hardened ink with PLTA Thinner in a portion of 10-20% max. In warm climates and in the presence of fine details or screened images the use of PLTD Retarder in a very small percentage is recommended.
WARNING: The life of the mixed ink is 8-10 hours after which the mechanical-chemical resistance and adhesion decrease. This is also dependent on room temperature and ratio of solvent.
WARNING: An excessive dilution causes a loss of coverage, smudges and incomplete ink detachment from the pad. A poor dilution may cause problems withdrawing ink from the cliché obtaining a repetitive print quality and avoiding the "dripping" of the same ink with lower print quality.
DRYING AND HARDENING: Generally the following drying times are applicable:
- Hand drying at 68 degrees F: Approx. 35 minutes
- Curing at 68 degrees F: Approx. 4-6 minutes
- Hand drying at 175 degrees F: Approx. 4-6 minutes
- Curing at 175 degrees F: Approx. 8-10 minutes
The final hardening of the ink is obtained after 24 hours. If the printed products require exceptionally high water resistance or resistance to other substances, the ink should be baked at 140 degrees C for 30-60 minutes.
RANGE OF COLORS: PLT4G is limited to 8 opaque colors as well as 3 transparent, four color process shades. Europa scale is available in the transparent colors. PLT4G has a high light fastness equivalent to 7-8 rating on the DIN 16525. PLT4G inks are adjusted for printing with PLTA Thinner, PLTCAN Fast Thinner, and PLT4D Retarder for printing fine detail.
PRINTING: PLT4G inks are available in transparent colors PLT4G #180 Yellow, PLT4G #181 Magenta, and PLT4G #182 Cyan.
STORAGE: PLT4G has a shelf life of about 2 years. Storage containers should be sealed and placed in a cool and dry place. PLT4GH Hardener should not be stored for long periods. The cans should be closed immediately after use, otherwise the hardener will take on moisture and become thick and useless.
