2. Chemical formula and molecular weight

● Chemical Name: Aspartic Acid, Polyaspartic Polyurea Resin

● CAS No.: 152637-10-0



3. Description

●FEISPARTIC F2850 is Aminofunctional co-reactant for polyisocyanates,it’s the
same model as NH2850 XP, could be used for the formulation of high-solids, two-
component polyurethane topcoats and solvent-free coating materials



● FEISPARTIC F2850 could serve as chain extender or R component in polyurea
coating. It could also react with –NCO functional HDI trimmer from which
longer gelling time and excellent yellow resistance can be achieved. Longer
gelling time can also be obtained when reacting with MDI pre-polymer. Hybrid of
polyurea and polyurethane can be achieved when FEISPARTIC F2850 is blended with
hydroxyl-functional resin such as acrylic, alkyd resin. FEISPARTIC F2850 offers
higher solid content and faster drying time than ordinary polyurethane. It is
widely applied on formulating variety of protective coatings.



● Main Feature

1. Lower viscosity, can be reactive diluent of polyaspartic ester resin
coatings.
2. Could be made into environmental coatings which has high solid content with
low viscosity.
4. Paint film has excellent combination of rebound resilience, leveling, gloss
and handfeel.
5. Paint film can offer excellent low temperature flexibility, waterproof and
solvent resistance as well as acid and alkali resistance etc.
6. Can react with our elastic curing agent to make elastic materials with
excellent mechanical properties of which elongation can reach to 400%.
