F520 Polyaspartic Ester Resin 
 
I Chemical formula and molecular weight 
- Chemical Name: Polayspartic Ester Resin, 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 
 
II Properties and application 
- F520 Polayspartic Ester Resin, is a solvent-free coating materials and a reactive partner for polyisocyanates. It's the same model as Germany brand NH1520, formulate high-solids, two-component polyurethane topcoats and solvent-free coating materials. 
- F520 Polayspartic Ester Resin 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 F420 and F524 to achieve a pure Polyaspartic polyurea coating with high build and fast dry two pack coating system  F520 Polayspartic Ester Resin 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. 
- Main Feature                                                        
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.
