ONE Chemical formula and molecular weight
Chemical Name: Aspartic Acid, N,N'-[methylenebis(2-methyl-4,1-cyclohexanediyl)]bis-, 1,1',4,4'-tetraethyl esterester
ELINCS No.: 412-060-9
CAS No.:  136210-30-5

TWO Properties and application
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.

MainFeature                                                                                                                                                               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
