- Features
It is a polyester based ink.Mono and two-component ink, good opacity and fast drying, good chemical resistance to oils, diluted acids, alkali and alcohol products, good adhesion, excellent resistance to abrasion, scratches and stacking. Non-toxic ink(NT) in compliance with European standard EN 71/part 3 and the European Directive 2011/65 /EC(RoHS 2). High light fastness.

- 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 (or TPH1) 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.
CAUTION!The catalyzed ink must be consumed within 6-8 hours or afterwards it gradually loses its mechanical-chemical resistanceandits ability toadhere 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.
DRYING AND HARDENING
The drying time lasts about 2 minutes at an ambient temperature of about 20 °C, but it increases with catalyst. 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.). Pot life (with catalyst) at ambient temperature 12-14 hours.
