WITCOBOND 457-66

WITCOBOND 457-66 is an aliphatic hydroxyl-functional polyurethane dispersion that produces high clarity, high performance protective topcoat finishes. It is a water-based, NMP-free dispersion that will cross-link with water reducible poly-isocyanates to form finished coatings. WITCOBOND 457-66 offers excellent performance properties for applications such as maintenance coating and concrete coatings. It provides benefits such as a tensile strength of 4500 psi, ultimate elongation of 90%, and hardness of 4H on pencil scale. WITCOBOND 457-66 withstands chemicals, abrasion and UV exposure very well as indicated by its test results. Its water-based and zero VOC formulation makes it suitable for industries that require protective and durable surface coatings with minimal environmental impact.
