FEISPARTIC® F421

FEISPARTIC® F421 by Shenzhen Feiyang Protech is a solvent-free polyaspartic polyurea resin and acts as an amino-functional co-reactant for polyisocyanates. It serves as a chain extender or R component in Spray Polyurea Elastic(SPUA). It exhibits low viscosity, high hardness up to 2H, and high reactivity to improve production efficiency. Suitable for the formulation of waterproof- and high-solid or solvent-free coatings.

• Its films offer excellent fullness, leveling performance and high gloss.
• It shows excellent weather-, water-, solvent-, abrasive-, acid- & alkali-, and salt spray resistance & other properties.
• It provides excellent adhesion with ABS, PC, PVC & other plastics and a variety of metals.
• It has excellent compatibility with most hydroxy acrylic resin and cab.
• It can not only be used with an elastic curing agent to manufacture elastic materials with excellent mechanical properties (elongation 400%, tensile strength 25MPa), but also reacts with a rigid curing agent, HDI Trimer (or dimer) to make rigid films (hardness 2H) & dries in 15 minutes.
• It is used in various high-grade paint fields such as automobile- and wood paints as it improves the fullness, gloss & hardness and speeds up the drying.
• It can be used in making anti-corrosion coatings for steel structures, oil pipelines and other light or heavy anti-corrosion fields.
• FEISPARTIC® F421 is be used for foam landscape, concrete waterproof materials, and other fields like floor- and wind-blade coating such as gel coat, putty & topcoat.
• It has a shelf life of 12 months.
