Customer Reviews
FEIYANG did offer their professional services and products to us. That is why we have had a long-term and stable business with them for several years. Nowadays, we are more like partners instead of just one of their distributors. Also, I hope we can expand markets in the future together.

—— USA Distributor

Feiyang is a reliable supplier, not only their product quality but also their professional technical support and service. We have done business together for six years already, which contributed to the growth of our business from nothing to several containers annually. We are so happy and lucky to have Feiyang as our partner.

—— European Distributor

We are very happy to be one of Feiyang's distributors in Australia. They are pretty nice supplier. They always do their best to meet our requirements. Our customers also trust Feiyang's high-quality product and out-standing service. Looking forward to developing more business together.

2.Properties of F520

FEISPARTIC F520 is an amino-functional co-reactant for polyisocyanates; it’s the same model as NH1520 and could be used to formulate 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. A longer gelling time can also be obtained when mixing with FEISPARTIC F420 to achieve a pure aspartic polyurea coating with a high build and a fast dry two-pack coating system. FEISPARTIC F520 is compatible with other hydroxyl-functional resins, such as acrylic and alkyd resin. It is widely applied in formulating a variety of protective coatings.


Polyaspartic ester polyurea resins react with polyisocyanates to create two-component polyurea/clear urethane coats.
Polyaspartic resins blend well with isocyanates for a more robust, more durable finish. The noted features they provide exterior coatings are weather and yellow resistance, zero VOCs (volatile organic compounds), and fewer coats that need to be applied to give more efficiency. End-users find freedom in a fast dry time, and it can be easily applied with standard equipment even though it has a high solid content. The advantages of using polyaspartic esters are the flexibility to design the reactivity to accommodate batch mixing and application, control over the cure rate when added to aliphatic coatings, and the ability to change the reaction time to extend the pot life. It can be customized to the needs of the application.


3. Storage 

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 original closed containers at 77°F (25°C).


4Polyaspartic Property Advantage

Property Polyaspartic polyurea Conventional polyurethane Spray polyurea
Environmental property Environmental friendly, construction solid content 70%-100% Poor environmental protection, construction solid content 30%-40% Good environmental protection, construction content 100%
Reaction speed Curing time adjustive,20min-4h, normally cure in 15-℃ Low reaction speed, request curing temperature above 5-℃, curing time more than 24h in normal temperature Rapid curing speed, from seconds to tens of seconds
Adhesion with substrate Don’t need primer; the adhesion with carbon steel substrate is beyond 14Mpa, and the bonding with concrete reaches 4.5Mpa. Need primer, adhesion with carbon steel substrate less than 8MPa, bonding with concrete is 2.5 Mpa. Need primer, low adhesion
Weather resistance QUVA test reaches 4000h QUVA test is 1000h at most Poor weather resistance, QUVA <200h
Film thickness One-time construction film 50μm—1mm One-time construction film 50μm——100μm One-time construction film 0.6mm-2mm
Mechanical properties Rigidity hardness 2H,elongation 400%, tensile strength 25MP Rigidity hardness 2H,elongation 400%, tensile strength 3MPa Same as aspartic polyurea
Construction Multiple construction methods get rid of the restriction of specified equipment. Same as aspartic polyurea Relying on sizeable special equipment
