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
