Yellow Resistance F2850 Polyaspartic Polyurea Resin
Polyurea technology and its related products were originated from the United States in 1981. The technology was patented by Bayer in 1992.
After years of research and development, polyurea materials has been developed from the first generation of aromatic spray polyurea and the second generation of aliphatic spray polyurea to the third generation of polyaspartate ester polyurea.
Polyaspartic polyurea belongs to premium innovative material, which is a new two-component polyurea material with adjustable curing speed, rigid and flexible, low temperature curing, super weather resistance, environmental protection and high performance.
On the one hand, it overcomes the defects such as the reaction rate of spraying polyurea system which is too fast to control, and the adhesion is poor and the construction depends on large equipment.
On the other hand, it also overcomes the defects of the traditional polyurethane coating system, such as higher VOCs content, low temperature curing, and baking equipment auxiliary curing.
Ⅰ Chemical formula and molecular weight
● Chemical Name: Aspartic Acid, Polyaspartic Polyurea Resin
● CAS No.: 152637-10-0
Ⅱ Properties and application
●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%.
