FEISPARTIC F2850 Solvent Free Polyaspartic Ester Resin
PROFILE
FEISPARTIC F2850 is a solvent-free aminofunctional co-reactant for polyisocyanates.
PROPERTY
- High solid content with low viscosity. Viscosity as low as 80 mPa.S. For the formulation of high-solid, two-component polyurethane topcoats and solvent-free coating materials.
- FEISPARTIC F2850's reaction activity is slower than FEISPARTIC F420. Significantly extend construction time.
- The coating film has excellent flexibility, leveling performance, gloss and hand feeling.
- FEISPARTIC F2850 can reaction with FEIYANG company’s elastic curing agent to make elastic materials with excellent mechanical properties.The elongation can reach 400%.
APPLICATIONS
- It can be used in various high-grade paint fields, such as automobile paint, high-grade wood paint and so on. It can obviously improve the fullness, luster, hardness of paint film and speed up the drying.
- It is used to make top coatings for steel structure, oil pipeline and other heavy and light anti-corrosion fields.
- It is used for making foam landscape, concrete waterproof material and other fields.
- It is used in the field of fan blade coating, such as gel coat, putty and topcoat.

Feiyang’s 26,000-Ton Polyaspartic Resin Expansion Project Completed
In July 2023, Feiyang launched the design and construction of a new 26,000-ton polyaspartic materials project. Upon full operation, the project will raise Feiyang’s total resin production capacity to 46,000 tons. It has significantly upgraded the original polyaspartic resin production process by establishing a fully automated production line that integrates raw material storage, manufacturing, and packaging. As a result, labor requirements have been reduced by 50%, while output per employee has doubled. In addition, the upgraded production line now enables the direct production of high-purity bio-based polyaspartic polyurea resin.
