66000 Series Polyurethane Screen Printing Ink – Air Dry

66000 Series Polyurethane Screen Printing Ink is a solvent-based, air-dry industrial ink built for flexible and hard-to-bond substrates. Its single-package polyurethane chemistry stays flexible and tough, so prints resist cracking and abrasion on materials that defeat ordinary inks — ideal for durable indoor/outdoor use.

⚠ Industrial use only. This is an industrial solvent ink for flexible plastics and industrial products. It is not a textile or garment ink and is not intended for printing on apparel or for skin contact.

Flexible, durable finish. Air dry. Quart, gallon and 5 gallon. Made in Hackensack, New Jersey.

Substrates & end uses — what the 66000 Series is for

A special-performance polyurethane ink formulated to flex and bond on demanding surfaces:

• Special-performance polyurethane
• Polyamide (nylon)
• Polyester
• Latex
• Leather

Chosen where prints must stay flexible and abrasion-resistant — flexible signage, industrial parts, and treated plastics that need a tough, durable film.

Match your 66000 Series ink with the correct retarder and cleaner. Add modifiers by weight and always test on your exact substrate first.

• OPTI 922 Biting Solvent & Retarder — add 3–5% for extra bite and adhesion on tough, flexible surfaces, and to slow drying.
• OPTI 974 Slow Thinner / Retarder — add 3–5% to extend open time in hot, humid conditions.
• OPTI 902 Lacquer Wash-Up or OPTI 925 Mild Lacquer Wash-Up — clean screens, squeegees and tools after printing.
