Detailed Product Description
F2872 = NH2872 LOW VISCOSITY POLYASPARTIC RESIN
F2872=NH2872 Low Viscosity Polyaspartic Polyurea Resin
Polayspartic polyurea technology is a core technology in our company. We have established a lab research base since 2004, with a strong R&D team consisting of 40 engineers. Now our polyaspartic polyurea materials have been applied on anti-corrosion, waterproof, flooring, construction coatings etc. We also can provide unique guide formulation to manufacturers based on their specified requirements.
Feiyang also set up a R&D institute located in Shenzhen University, equipped with advanced testing and researching machines. With continuous development of well-sold special chemical, the institute has built great cooperative relationships with Stanford (US), Dalian Univesity of Technology and Shanghai Jiaotong University.
Ⅰ Chemical formula and molecular weight
● Chemical Name: Aspartic Acid, Polyaspartic Polyurea Resin
Ⅱ Properties and application
●FEISPARTIC F2872 is Aminofunctional co-reactant for polyisocyanates,it’s the same model as NH2872 XP, could be used for the formulation of high-solids, two-component polyurethane topcoats and solvent-free coating materials
● FEISPARTIC F2872 could serve as chain extender or R component in polyurea coating. It could also react with –NCO functional HDI trimmer from which longer gelling time and excellent yellow resistance can be achieved. F2872 could be applied to high solid anti-corrosion coating, high flexibility waterproofing coating, solvent free sealant and high rebound elasticity flooring coating.
●Main Feature
1. Lower viscosity, can be reactive diluent in Polyaspartic system
2. Could be made into environmental coatings which has high solid content with low viscosity.
3. The reactivity is modest, could be used to extend working time
4. Providing excellent hardness, leveling property, gloss and touch feel to the coating
5. Paint film can offer excellent low temperature flexibility, waterproof and solvent resistance as well as acid and alkali resistance etc.
6. Can react with our elastic curing agent to make elastic materials with excellent mechanical properties of which elongation can reach to 400%.

Polyaspartic Property Advantage
| Property | Polyaspartic polyurea | Conventional polyurethane | Spray polyurea |
| Environmental property | Environmental friendly, construction solid content 70%-100% | Poor environmental protection, construction solid content 30%-40% | Good environmental protection, construction content 100% |
| Reaction speed | Curing time adjustive,20min-4h, normally cure in 15-℃ | Low reaction speed, request curing temperature above 5-℃, curing time more than 24h in normal temperature | Rapid curing speed, from seconds to tens of seconds |
| Adhesion with substrate | Don’t need primer, the adhesion with carbon steel substrate is beyond 14Mpa, the adhesion with concrete reach 4.5Mpa. | Need primer, adhesion with carbon steel substrate less than 8MPa, adhesion with concrete is 2.5 Mpa | Need primer, low adhesion |
| Weather resistance | QUVA test reach 4000h | QUVA test is 1000h at most | Poor weather resistance,QUVA ＜200h |
| Film thickness | One time construction film 50μm&sh;1mm | One time construction film 50μm&sh;&sh;100μm | One time construction film 0.6mm-2mm |
| Mechanical properties | Rigidity hardness 2H,elongation 400%, tensile strength 25MP | Rigidity hardness 2H,elongation 400%, tensile strenght 3MPa | Same as aspartic polyurea |
| Construction | Multiple construction method, get rid of the restriction of specified equipment | Same as aspartic polyurea | Relying on large special equipment |
