FEISPARTIC F421 Polyaspartic Ester Resin
ⅠChemical formula and molecular weight
● Chemical Name: Polyaspartic Ester Resin, Aspartic Acid, N,N'-(methylenedi-4,1-cyclohexanediyl)bis-,1,1',4,4'-tetraethyl ester
● ELINCS No.: 429-270-1
● CAS No.: 136210-30-5
ⅡProperties and application
● FEISPARTIC F421 Polyaspartic Ester Resin is a solvent free amine-functional resin.. It is a aspartic ester polymer as reactive partner for polyisocyanates. It’s the same model as NH1420, formulate high-solids, two-component polyurethane topcoats and solvent-free coating materials.Comparing Feiyang F420, F421 potlife is much longer.
● It can serve as chain extender or R component in polyurea coating.
It can 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 reacted with MDI pre-polymer. Hybrid of polyurea and polyurethane can be achieved when F421 is blended with hydroxyl-functional resin e.g acrylic, alkyd. This can offer high solid content and faster dry time than ordinary polyurethane. It is widely used in protective /floor / elastic/weather resistant coating, waterproof, etc.
● Main Feature 1. High solid content with low viscosity. 2. Faster curing time in aliphatic system.
3. Offering excellent physical properties like high hardness, flexibility, elongation(400%), tear and tensile strength(25MPa). 4. Great weather and saline water resistance.
5. Cost efficiency.
