DURA PU 101

Polyurethane plasticizer

Description

DURA PU 101 is a non-reactive thermoplastic polyurethane resin and is suited to modifying nitrocellulose-based inks for flexo and gravure applications on flexible substrates.

Properties

Polyurethane resins impart excellent adhesion to numerous flexible films and offer good heat-seal jaw release with resistance to blocking, deep-freeze, oils, fats, and water.

Applications

DURA PU 101 is suitable for use in nitrocellulose coating and ink applications where excellent flexibility, adhesion, and deep freeze resistance are required.

CHARACTERISTICS

• Soft and flexible with high gloss.
• Can be used alone or in combination with a monomer plasticizer.
• Excellent evaporation and low solvents retentions.
• Excellent compatibility with alcohol.
• Excellent unfastening of the thermosealing clips.
• Excellent adhesion to polyolefin films. Resistance to oils, fats, water, and freezing.
• Excellent compatibility with NC, PVB, Ketones, maleic resins
