Qtech-404 Mining Equipment Ultra Anti-Abrasion Polyurea Material

PRODUCTION INFORMATION
 
Production Description
Qtech-404 Mining Equipment Ultra Anti-Abrasion Polyurea Material 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-404 is used by itself or in combination with other materials to produce coatings, liners, wearing courses, and resilient surface on mining equipment surface and other substrates. Qtech-404 can produce an extremely tough film at all thicknesses; it may be applied in all positions and to any suitably prepared substrate. Qtech-404 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 coating surfacing system which exhibits extraordinary performance characteristics.
 
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’s, Odorless, No Toxic Vapors.
6. Good resistance to a wide range of chemical attack.
7. Excellent Abrasion resistance and Impact resistance.
8. Good weather ability, Added color stability.
9. Seamless, flexible, slick and non-porous.
10. No chalking and fading in long-term use outdoors.
 
Recommended Uses
Qtech-404 Mining Equipment Ultra Anti-Abrasion 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 Mineral Equipment, Mineral Processing, Vibration Screen, Ore Washing Roll, Flotation Cell, Ore Bucket; it can also be applied in: Spiral Separator, Pipe Coatings, Grinding Plants, Marine Steel Structure, Truck Bed Liners and so on.
