2. Chemical formula and molecular weight
● Chemical Name: Aspartic Acid, Polyaspartic Polyurea Resin, N, N'-[2-methy-1,5-pentanediyl)]bis-, 1,1',4,4'-tetraethyl Ester
● ELINCS No.: 433-260-2
● CAS No.: 168253-59-6
3. Properties and application
● FEISPARTIC F220, a solvent-free amine-functional resin, is a reactive partner for polyisocyanates. FEISPARTIC F220 is the same model as NH1220, and it could be used to formulate rigid but flexible, lightfast, and highly reactive two-component polyurethane spray coatings.
●FEISPARTIC F220 can be applied in SPUA (spraying elastomeric polyurea) R component as chain extender and main resin, FEISPARTIC F220 can be used to formulate anti-corrosion coatings for the protection of steel structures, oil pipelines, bubble landscape, concrete waterproofing materials.
● Main Feature
1. 100% high solid resin,
2. Faster drying time, Touch dry time with HDI is 5min,
3. Excellent flexibility, Good leveling properties,
4. Great weather, water, and chemical resistance,
5. Excellent wearing resistance (abrasion loss ≤ 20 mg
(500r/750g)),
6. Good adhesion on plastics, e.g., ABS, PC, PVC, and various
metals.
4. 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 |
