F-520 an amine-functional aspartic ester resin, is a solvent-free coating materials and a reactive partner for polyisocyanates. It’s the same model as NH1520, formulate high-solids, two-component polyurethane topcoats and solvent-free coating materials.

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 mixing with F-420 and F-524 to achieve a pure aspartic polyurea coating with high build and fast dry two pack coating system  F-520 is also compatible with other hydroxyl-functional resin e.g acrylic, alkyd.  It is widely used in protective /floor / elastic/weather resistant coating, waterproof, etc.
