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.

FEISPARTIC F421 Polyaspartic Resin 800-2500 Viscosity



FEISPARTIC F421 is aminofunctional co-reactant for polyisocyanates.



  • Solvent-free with low viscosity. For the formulation of high-solid or solvent-free coatings.
  • High reactivity to improve the production efficiency. React with HDI Trimer and dry in 15 minutes.
  • The coating film has excellent fullness, leveling performance and high gloss.Has excellent weather resistance, water resistance, solvent resistance, acid and alkali resistance, salt spray resistance and other properties. High hardness up to 2H and excellent abrasive resistance.
  • Excellent adhesion with ABS, PC, PVC and other plastics and a variety of metals.
  • FEISPARTIC F421 has excellent compatibility with most of hydroxy acrylic resin and cab.
  • It can not only be used with our elastic curing agent to make elastic materials with excellent mechanical properties (elongation 400%, tensile strength 25MPa), but also can be used with rigid curing agent, HDI Trimer (or dimer) to make rigid film (hardness 2H).
  • Serve as chain extender or R component in Spray Polyurea Elastic(SPUA).



  • For various high-grade paint fields, such as automobile paint, wood paint and so on. It can obviously improve the fullness, gloss and hardness and speed up the drying.
  • It is used to make anti-corrosion coatings for steel structure, oil pipeline and other light or heavy anti-corrosion fields.
  • Can be used for foam landscape, concrete waterproof materials and other fields.
  • Can be used for wind blade coating field, such as gel coat, putty and topcoat.
