1) Introduction of Shenzhen Feiyang Protech Corp., Ltd.


Shenzhen Feiyang Protech Corp., Ltd. is a holding company of FEIYANG GROUP (founded in 1992). It is China's national high-tech leading polyaspartic material researcher and manufacturer with robust R&D. Feiyang is the first and unique Polyaspartic Ester Resin researcher and manufacturer in China.

With 20 years of development, Feiyang owns many technology patents; Feiyang summarized and popularized Polyaspartic Polyurea Materials applications on anti~corrosion, waterproof, construction coatings, and matured guide formulations can be offered on each application series. Feiyang has now supplied poly aspartic resin and hardeners to more than 30 countries and 200 customers globally.


2) Chemical formula and molecular weight
● Chemical Name: Aspartic Acid, N,N'-(methylene-4,1-cyclohexanediyl)bis-,1,1',4,4'-tetraethyl ester

● ELINCS No.: 429-270-1

● CAS No.: 136210-30-5

3) Properties and application
F421 is a solvent-free amine-functional resin. It is an aspartic ester polymer as a reactive partner for polyisocyanates. It's the same model as NH1420, formulating high-solids, two-component polyurethane topcoats, and solvent-free coating materials. Comparing Feiyang F420, the F421 pot life is much longer.
● It can serve as a 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. A hybrid of polyurea and polyurethane can be achieved when F421 is blended with hydroxyl-functional resin, e.g., acrylic or 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.​
4) Main Feature
1. High solid content with low viscosity.
2. Faster curing time in the 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.
5. Cost efficiency.
5) Quality standard
