FEISPARTIC F221 Abrasion Resistance Polyaspartic Polyurea Resin
1. 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 |
2. Chemical formula and molecular weight
Chemical Name: Aspartic Acid, Polyaspartic Polyurea Resin
3. Properties and application
● FEISPARTIC F221 is an amino-functional co-reactant for polyisocyanates and is specifically designed to cure with standard HDI Trimer Isocyanates for industrial flooring applications
● FEISPARTIC F221 preferred hardeners are standard and low-viscosity HDI trimer isocyanates for various industrial applications. Clear and pigmented topcoats and filled self-leveling systems based on FEISPARTIC F221 support high aesthetics, UV stability, and rapid property development for fast return to service. FEISPARTIC F221 is free of solvents, alkyl phenol derivatives, and benzyl alcohol.
