Product Info for UNITHANE IC-151 NF


UNITHANE IC-151 NF is an anionic APEO free dispersion of an aliphatic polyester-based urethane in water. UNITHANE IC-151 NF is designed for industrial coating applications requiring good gloss, chemical resistance and adhesion to a variety of substrates.


UNITHANE IC-151 NF polyurethane dispersion can be compounded for a number of industrial coating applications: including clear, hard coatings for plastics, untreated aluminum, treated steel and concrete floor coatings.

The performance of UNITHANE IC-151 NF can be further enhanced by blending with other Union polyurethane dispersions or by the use of external crosslinking like: polyfunctional aziridines, water dispersible isocyanates or polyfunctional carbodiimides.

Industrial Applications:

This product is recommended for: Paint and Coating Resins
