| Description: | F-420 Amine-Functional Aspartic Ester Resin 1. DESCRIPTION USES F-420 is a solvent free amine-functional resin.. It is a aspartic ester polymer as reactive partner for polyisocyanates, the same model as Bayer NH1420. 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 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. 2. FEATURES High solid content with low viscosity Faster curing time in aliphatic system Offering excellent physical properties like high hardness, flexibility, elongation(400), tear and tensile strength(25MPa). Great weather and saline water resistance Cost efficiency 3.
