It is the state of the art 100% solids, ultra fast cure, flexible, spray-applied, high build, and two components aromatic pure polyurea elastomer. The system consists of A component, a quasi-prepolymer rich of free NCO, and B component, a mixture of polyetheramines, amine extenders and other additives. Qtech-412 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-412 can produce an extremely tough film at all thicknesses; it may be applied in all positions and to any suitably prepared substrate. Qtech-412 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. Advantages 1. Anti- collision, Impact resistance, Impermeable, Abrasion resistant 2. Bondable and paintable to various kinds of substrates 3. Fast cure, short down time, no sagging 4. Excellent Physiochemical Properties 5. Ambient insensitive, good thermal stability 6. 100% Solids, No VOC’s, Odorless, No Toxic Vapors 7. Good resistance to a wide range of chemical attack 8. Good weather ability, Added color stability 9. Wide service temperature (-45~150 degree centigrade) 10. Seamless, flexible, slick and non-porous 11. No chalking and fading in long-term use outdoors Recommended Uses: Qtech-412 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.
