Product Description

Production Description： Qtech***2 Coastal Dam Polyurea Protective Material is independently developed by Qingdao Shamu International Trade Co., Ltd. It is the state of the art **0% solids, ultra fast cure, flexible, spray-applied, high build, and two components aromatic pure polyurea elastomer.Qtech***2 is used by itself or in combination with other materials to produce dam protective coatings, anti collision liners, reinforcing layer, and resilient surface on concrete, stone and other substrates. Qtech***2 can produce an extremely tough film at all thicknesses; it may be applied in all positions and to any suitably prepared substrate. Qtech***2 can effectively decrease the impact of tidewater to dam, improve the imperviousness, prevent floods and debris flow damage and improve the safety and durability of dams. Recommended Uses: Qtech***2 Coastal Dam Polyurea Protective Material is an ultra fast cure system; it can be applied at thicknesses of several ten millimeters, or greater, in a single application. It can be widely used in Coastal dam, Buttress dam, Overflow dam, Flood-discharge tunnel, Desilting tunnel, Water diversion canal, Flood embankment and Flood discharge facility coordination.
