It is the state of the art 100% solids, ultra fast cure, flexible, spray-applied, high build, and two components aliphatic 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-411 is an aliphatic polyurea elastormeric which is color fast and resist yellowing.Qtech-411 is extremely stain resistant with a high gloss finish and displays excellent UV weathering characteristics. It is used by itself or in combination with other materials to produce ultra weather coatings, liners, wearing courses, and resilient surface on bridge concrete and other substrates. Qtech-411 can produce an extremely tough film at all thicknesses; it may be applied in all positions and to any suitably prepared substrate. Qtech-411 is relatively moisture and temperature insensitive, allowing applying in the most problematic ambient conditions. It is the optimum choice for tough, flexible, color stability, anti-corrosion system to bridge painting. Advantages; 1. Fast cure, short down time, no sagging 2. Excellent Physiochemical Properties 3. Bondable and paintable to various kinds of substrates 4. Ambient insensitive, good thermal stability 5. 100% Solids, No VOC, Odorless, No Toxic Vapors 6. Good resistance to a wide range of chemical attack 7. Anti-corrosion, Skidding resistance, Impermeable, Abrasion resistant 8. Good weather ability, Added UV Stability 9. Seamless, flexible, slick and non-porous 10. No chalking and fading in long-term use outdoors Recommended Uses: Qtech-411 Bridge Ultra-Weather Resistant Polyurea 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 Bridge Tower, Exposed Signs and Displays, Architectural Finishes; it can also be applied in Over Urethane Form Roofing, Over Metal or Concrete Roofing, Urban Landscape, Metal Fabrication and Online Shop Painting and Industries, Amusement and Water Park Equipment and Rides.
