InstaCure UltraFlex is an extremely flexible, yet provides a hard – durable and scratch resistant surface.  This is a  100% solids UV curable clear coat, specially formulated for use on applications requiring additional elongation.  This product is particularly suitable for paper products in the packaging marketplace, such as card stock and corrugated paper, in addition to many plastic, styrene and other related products used in packaging..  Perhaps one of this products’ greatest attributes is its ability to adhere to low surface energy substrates.
