Bayer Nh1520 Polyaspartic Polyurea Resin Alternative Feiyangchem F520 - China

F-520 Amine-Functional Aspartic Ester Resin

1 - DESCRIPTION & USES

F-520 , an amine-functional aspartic ester resin, is a solvent-free coating materials and a reactive partner for polyisocyanates.

The same model as Bayer NH1520.

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.

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
