Polyurea is produced by reacting a resin with an amino group with an isocyanate curing agent, which contains repeating urea-based chain segments in its molecular structure.
Structure of urea-based chain segments
Polyaspartic polyurea is the third generation of new polyurea after aromatic polyurea and aliphatic polyurea. Polyaspartic polyurea is a resin containing a urea bond that is produced by reacting the secondary amine group on the polyaspartic resin with an isocyanate.

As a high-performance resin material that has been industrialized, polyaspartic polyurea has a wide range of uses. At present, it is mainly used as the main body-resin of coatings and applied to waterproof coatings, anticorrosive coatings, floor coatings, industrial coatings and other fields. It can also be applied in the fields of seam sealer, potting compound, adhesive, pouring material, etc.
Feiyang specializes in the research, development, production and sales of polyaspartic polyurea materials. The main products are polyaspartic resins. After more than 30 years of development, we have now obtained more than 300 technical patents, and our market share in China is more than 65%. Our aim is to provide the coating industry with "environmentally friendly, energy-saving, long-lasting" raw materials and coating solutions, and to be the global R&D and technical solution provider of polyaspartic polyurea materials.
