Polyaspartic Resin
Feispartic F423
Alternative to Desmophen® NH 1423
FEISPARTIC F423 is a high-purity, solvent-free, low-viscosity aminofunctional co-reactant for polyisocyanates, with very low diethyl fumarate content. Designed for high-solids and solvent-free coating systems, it offers fast reaction with HDI trimer, excellent film build, leveling, gloss, adhesion to plastics and metals, and durable resistance to weathering, water, solvents, chemicals and salt spray.

Applications
- Suitable for various high-end coating applications, such as automotive coatings and wood coatings. It helps improve film build, gloss, hardness and drying speed.
- Used in anti-corrosion coatings for steel structures, oil pipelines and other light- to heavy-duty protective coating applications.
- Suitable for foam landscape coatings, concrete waterproofing materials and other construction-related systems.
- Used in wind turbine blade coating systems, including gel coats, putties and topcoats.
Packing & Storage Information
Packing
200 Kgs/Drum, 20 Kgs/Drum
Shelf Life
FEISPARTIC F423 must be stored in airtight containers to prevent contact with moisture. Recommended storage temperature is below 40°C (≤104°F). The shelf life in the closed original container is 12 months.
Notice
- FEISPARTIC F423 is combustible and should be stored at a temperature below 40 ℃. It should be kept away from fire source and stored in a cool, dry and ventilated environment. The storage period is 12 months.
- The coating formulated with FEISPARTIC F423 should be tested for performance after one week’s maintenance.
