Qtech-409 Armored Underpan Anti-Collision & Friction Polyure


Qtech-409 Armored Underpan Anti-Collision & Friction Polyurea Material

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.
1. Fast cure, short down time, no sagging.
2. Excellent Physiochemical Properties.
3. Ultra High-Strength and High-Elongation.
4. Bondable and paintable to various kinds of substrates.
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.
