FEISPARTIC F420=NH1420 High Solid Polyaspartic Polyurea Resin
● FEISPARTIC F420 could be a polyurea coating, a chain extender, or an R component. It could also react with –NCO functional HDI trimmer from which a longer gelling time and excellent yellow resistance can be achieved. Longer gelling time can also be obtained when reacting with MDI pre-polymer. A hybrid polyurea and polyurethane can be completed when FEISPARTIC F420 is blended with a hydroxyl-functional resin such as acrylic and alkyd resin; FEISPARTIC F420 offers higher solid content and faster drying time than ordinary polyurethane. It is widely applied in formulating a variety of protective coatings.
● Main Feature
1. High solid content with low viscosity
2. Faster curing time in the aliphatic system
3. Offering excellent physical properties like high hardness, flexibility, elongation(400%), tear, and tensile strength(25MPa).
4. Great weathering and saline water resistance
Ⅲ Quality standard

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, and the bonding with concrete reaches 4.5Mpa. | Need primer, adhesion with carbon steel substrate less than 8MPa, bonding with concrete is 2.5 Mpa. | Need primer, low adhesion |
| Weather resistance | QUVA test reaches 4000h | QUVA test is 1000h at most | Poor weather resistance, QUVA ＜200h |
| Film thickness | One-time construction film 50μm—1mm | One-time construction film 50μm——100μm | One-time construction film 0.6mm-2mm |
| Mechanical properties | Rigidity hardness 2H,elongation 400%, tensile strength 25MP | Rigidity hardness 2H,elongation 400%, tensile strength 3MPa | Same as aspartic polyurea |
| Construction | Multiple construction methods get rid of the restriction of specified equipment. | Same as aspartic polyurea | Relying on sizeable special equipment |
