TWO Properties and application

F420 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 Bayer Domesphen NH1420, formulate high-solids, two-component polyurethane topcoats and solvent-free coating materials.
F420 Polyaspartic Ester Resin 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 F420 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
