F2872=NH2872 Polyaspartic Polyurea Resin High-solid Content
There is a development of a new class of aliphatic polyurea polymer systems. These systems are based on the reaction of polyaspartic ester compounds (a type of secondary aliphatic amine with aliphatic polyisocyanate). Polyaspartic ester-based polyurea topcoats are non-yellowing and exhibit good outdoor weathering and long pot life. The moderately fast reactivity, combined with the relatively low viscosity of the polyaspartic ester compounds, allows for a broader range of applications in two-component coatings.
Ⅰ Chemical formula and molecular weight
● Chemical Name: Aspartic Acid, Polyaspartic Polyurea Resin
Ⅱ Properties and application
●FEISPARTIC F2872 is Aminofunctional co-reactant for polyisocyanates,it’s the same model as NH2872 XP, could be used for the formulation of high-solids, two-component polyurethane topcoats and solvent-free coating materials
● FEISPARTIC F2872 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. F2872 could be applied to high solid anti-corrosion coating, high flexibility waterproofing coating, solvent free sealant and high rebound elasticity flooring coating.
1. Lower viscosity, can be reactive diluent in Polyaspartic system
2. Could be made into environmental coatings which has high solid content with low viscosity.
3. The reactivity is modest, could be used to extend working time
4. Providing excellent hardness, leveling property, gloss and touch feel to the coating
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%.
