Isopave® Doublemax is a two-component flexible gravel binding resin developed for medium pedestrian loads. It does not yellow due to its aliphatic polyurethane structure. The resin and hardener shipped as two components are mixed in ready-made proportions and then applied by mixing method. The usage rate is between 3-5% of the gravel weight depending on the gravel size and the dust contained in the gravel. Drying time is shorter than Isopave® Ultramax time.
