PLT 31 TECHNICAL DATA SHEET

APPLICATIONS
Suitable for leather, synthetic leather, polyamides, treated PE and PP, polyurethane, self-adhesive pvc, plasicized pvc, hard pvc, lacquered surfaces.

FEATURES
Vinyl based ink.

Mono and bicomponent ink semi-glossy appearance with good opacity and good resistance to weathering. It is not suitable for prints that need to be exposed outside for long periods (3-5 years).

Excellent resistance to alcohol. The addition of the catalyst (PLHN / PLH, to the extent of 10%) also enhances the resistance to other agents, such as gasoline. Non-toxic ink (NT) in compliance with European standard EN 71 / part 3 and with the 2011/65/EC European Directive (RoHS 2).

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 PLHN/ 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 cm2) 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 itis advisabletorenew the ink approximately every 4/8 hours of work.

Excessivedilutiongenerates aloss of thecovering power, smudges and an imperfect detachment of theink from the pad. Aninsufficient dilutioncauses problems of drawing the ink from the cliché, printing repeatability and dripping of the ink with aconsequent decline of the printing quality.

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.
