ESACOTE® PU 4045

ESACOTE® PU 4045 by Lamberti is a multipurpose, low VOC, anionic waterborne dispersion of an aliphatic polyurethane based on polyester diols. It is used as a binder for clear & pigmented coatings and for primer in digital water-based printing. It forms transparent films with some residual stickiness and without the need of co-solvent.

• It provides good intercoat adhesion, good compatibility with inorganic salts (like calcium chloride), and good adhesion properties to a large variety of substrates.
• It is suitable for flexo- and rotogravure lamination inks with good compatibility with pigmented pastes.
• ESACOTE® PU 4045 can be used as sole binder or in combination with other water-based resins.
• It can be combined with water dispersible polyisocyanates, polyaziridines or carbodiimides crosslinkers to enhance the overall properties.
• It has a shelf life of 12 months.
