- Features
It is a Vinyl – polyester based ink. Mono and bi-component ink, glossy appearance with good opacity and fast drying. It is not suitable for prints that need to be exposed outside. Excellent resistance to alcohol. Non-toxic ink (NT) in compliance with European standard EN 71 / part 3and with the 2011/65/EC European Directive (RoHS 2).
CAUTION!
The catalyzed ink must be consumed within 6-8 hours or afterwards it gradually loses its mechanical-chemical resistance and its ability to adhere to the support. For uniform production quality it is advisable to renew the ink approximately every 4/8 hours of work. Excessive dilution generates a loss of the covering power, smudges and an imperfect detachment of the ink from the pad. An insufficient dilution causes problems of drawing the ink from the cliché, printing repeatability and dripping of the ink with a consequent decline of the printing quality.

PROCESSING
To increase the mechanical and chemical resistance or adherence to the support, the ink can be used as a two-component ink by adding the special PLH catalyst in a 10:1 ratio (10 parts ink and 1 part catalyst). Mix and strongly dilute the ink by using the PLA thinner in the measure of max. 10-20%. When printing fine details or screened images(e.g. 80/120 lines per cm^2) in warm environments, we recommend you add the PLD retardant in a minimum percentage.
DRYING AND HARDENING
The drying time is from 10 to 15 minutes at an ambient temperature of about 20°C. 5 minutes with hot air flow. If you would like it to dry in only a few time, you can use hot air circulation ovens (60-80 °C) or high temperature spot devices (air or infrared rays) that can be installed on the piece feeding systems (e.g. rotary tables, conveyors, etc.). The ink is completely hardened after 6-7 days of application. Pot life at ambient temperature 6-8 hours.
