ESACOTE® PU 77

ESACOTE® PU 77 by Lamberti is a multipurpose, low VOC, anionic waterborne dispersion of an aliphatic polyurethane based on polycarbonate diols. It is used as a binder for clear and pigmented coatings, providing good balance of elasticity & hardness, high gloss & clarity, excellent flow & leveling, and mechanical- & chemical resistance. It forms tough, transparent & glossy films and allows good film formation when used with small percentage of glycols.

• It is used in wood coatings (parquet and furniture topcoat) and in metal coatings for pretreatment on different substrates (galvalume, galvanized iron, aluminum or cold rolled steel).
• It is recommended for plastic films (ex. PVC) as OPV anti-scratch varnish.
• In architectural coatings, it is suitable as topcoat for flooring 2K on concrete.
• It improves the adherence on porous substrates, and offers high lamination strength in flexo- & rotogravure inks.
• It can be combined with water dispersible polyisocyanates, melamine resins, polyaziridines or carbodiimides crosslinkers to enhance the overall properties.
• ESACOTE® PU 77 has a shelf life of 12 months.
