PRODUCTION INFORMATION
Production Description
Qtech-409 Armored Underpan Anti-Collision & Friction Polyurea Material is the state of the art 100% solids, flexible, spray-applied, high build, two components, fast set, and 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. This ultra high-strength, high-elongation polyurea can be sprayed onto virtually any surface configuration and to any thickness. It is excellent for interior and exterior applications. Qtech-409 is used by itself or in combination with other materials to produce armored under pan anti collision and friction coatings, liners, wearing courses, and resilient surface. Qtech-409 can produce an extremely tough film at all thicknesses; it may be applied in all positions and to any suitably prepared substrate. Qtech-409 is relatively moisture and temperature insensitive, allowing application in the most problematic ambient conditions. It is the optimum choice where a tough, flexible, impact resistant, abrasion resistant, anti-collision, skidding resistant surfacing system which exhibits extraordinary performance characteristics.

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. Anti-corrosion, Skidding resistance, Impermeable, Abrasion resistant.
9. Seamless, flexible, slick and non-porous.
10. No chalking and fading in long-term use outdoors.
Recommended Uses
Qtech-409 Armored Underpan Anti-Collision & Friction 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 metal and hard things striking together, it can also prevent hail attack; It can be widely used in: Armored Underpan, Air Mattress, Fender, Drifting Buoy, Chutes and Hoppers, Silos, Screw Conveyors, Cyclones; it can also be applied in Aviation, Aerospace, Construction and Military.

Notes
1. Qtech product is intended for industrial use by properly trained professional applicators only.
2. Thoroughly mix container of B component with an air-driven power mixer for a minimum of 15 minutes prior to application.
3. Adding a nitrogen blanket is strongly recommended for use on the "A" component for storage after opening.
4. It is a 100% solids production, strictly prohibit add any diluents.
5. The quality and fitness of the product is depending upon the proper mixture and application of the component by the applicator.
6.This specification is an accumulation of long term testing and experience. Published technical data and instructions are subject to change without notice.
