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. Chemical formula and molecular weight

● Chemical Name: Aspartic Acid, Polyaspartic Polyurea Resin

CAS No.: 152637-10-0


3. Description

FEISPARTIC F2850 is an amino-functional co-reactant for polyisocyanates; it’s the same model as NH2850 XP and could be used for the formulation of high-solids, two-component polyurethane topcoats, and solvent-free coating materials


FEISPARTIC F2850 could serve as a polyurea coating chain extender or R component. It could 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 reacting with MDI pre-polymer. A hybrid polyurea and polyurethane can be completed when FEISPARTIC F2850 is blended with a hydroxyl-functional resin such as acrylic and alkyd resin. FEISPARTIC F2850 offers higher solid content and faster drying time than ordinary polyurethane. It is widely applied in formulating a variety of protective coatings.


● Main Feature

1. Lower viscosity can be a reactive diluent of polyaspartic ester resin coatings.
2. Could be made into environmental coatings with high solid content and low viscosity.
4. Paint film combines rebound resilience, leveling, gloss, and hand feel.
5. Paint film can offer excellent low-temperature flexibility, waterproof and solvent resistance, acid and alkali resistance, etc.
6. We can react with our elastic curing agent to make flexible materials with excellent mechanical properties, of which elongation can reach 400%.


4. Polyaspartic 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
