TECHNICAL DATA SHEET PLT18 INK

APPLICATIONS
Used for cellulose acetate, duroplastics, polyamide and polyester, treated PE and PP, metal and varnished surfaces.

FEATURES
Epoxy based ink.

It is a two-component ink.

It has a matt appearance and an excellent covering power and is quick-drying.

Non-toxic ink (NT) conforms to European regulations EN 71/part 3 and European Directive 2011/65/EC (RoHS 2).

It has a very good mechanical and chemical resistance to many organic solvents, chemical solvents, acids, diluted alkali, oils and greases.

PROCESSING
Add the special PLH (or PLH/219) catalyst in a  20% ratio.

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!

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.

The catalyzed ink must be consumed within 8-10 hours or afterwards it gradually loses its mechanical-chemical resistance an its ability to adhere to the support.
 

DRYING AND HARDENING
The drying time lasts between 10 and 15 minutes at an ambient temperature of about 20 °C.

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 24/48 h.
