PN Series – Proposition 65 compliant Ink for Polypropylene, Polyurethane, Metal & More

PN series is a specialty pad and screen-printing ink designed for printing on treated and untreated polypropylene, treated polyester, metal, lacquered surfaces, and polyurethane. Unlike other polypropylene inks, PN Series is Proposition 65 compliant. The PN Series is available in standard mixing, high density (HD), and metallic colors. This high gloss ink withstands 50 alcohol wipes without hardener and 100 wipes with hardener.

Substrates: Typical Applications:
Treated and Untreated Polypropylene
Treated Polyester
Lacquered Surfaces
Promotional products
Syringes & Medical Devices
Industrial Housings

Mixing Preparation
(1- or 2-Component Ink)

Hardeners: PN Series pad printing/ screen printing ink can be used with or without hardener. Adding 1000-H in the ratio of 10% significantly increases abrasion resistance. PN Series ink has a working pot-life of 6-8 hours.

Solvent: Immediately after adding the hardener the mixture should be thinned to printing viscosity with 10%-30% Type: M, MS, EB, or S3 by weight. Adding solvent will make the ink less viscous and dry slower.

Drying: PN Series ink for treated and untreated polypropylene, treated polyester, metal, lacquered surfaces and polyurethane cures by either air drying at room temperature (10-15 mins) or with warm air circulation (about 122°F for 5 mins.) Polymerization is complete at room temperature 6-7 days after the ink is applied.

Retarder: For fine prints, add Type MS retarder in proportions not to exceed 50% by weight of solvent. Adding too much retarder may inhibit ink transfer from pad to substrate.
