Polyaspartic polyurea resin FEISPARTIC F520

Ⅰ、Chemical formula and molecular weight

● Chemical Name: Aspartic Acid, Polyaspartic Polyurea Resin, N,N’-［methylenebis(2-methyl-4,1-cyclohexanediyl)］bis-, 1,1’,4,4’-tetraethyl ester

● ELINCS No.: 412-060-9 

● CAS No.: 136210-32-7

Ⅱ、Properties and application
● FEISPARTIC F520 is Aminofunctional co-reactant for polyisocyanates,it’s the same model as NH1520, could be used for the formulation of high-solids, two-component polyurethane topcoats and solvent-free coating materials.

● FEISPARTIC F520 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 FEISPARTIC F420 to achieve a pure aspartic polyurea coating with high build and fast dry two pack coating system.FEISPARTIC F520 is also compatible with other hydroxyl-functional resin such as acrylic, alkyd resin.It is widely applied on formulating variety of protective coatings.

● 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 weathering and saline water resistance

Ⅲ、Quality standard

Ⅳ、Package and storage
● 200Kgs/Drum,4Drums/pallets,80Drums/container or 1Ton/IBC tank.
● FEISPARTIC F520 resin must be stored in tightly sealed containers to prevent from contacting with moisture.
Recommended storage temperatures are 0°-40°C (32°-104°F).
The shelf life of FEISPARTIC F520 is 12 months when stored in closed original containers at 77°F (25°C).
