FEISPARTIC F420 High Solid Polyaspartic Polyurea Resin
Ⅰ Chemical formula and molecular weight
● Chemical Name: Aspartic Acid, Polyaspartic Polyurea Resin, N, N'-(methylene-4,1-cyclohexanediyl)bis-,1,1',4,4'-tetraethyl ester
● ELINCS No.: 429-270-1
● CAS No.: 136210-30-5
Ⅱ Properties and application
●FEISPARTIC F420 is an amino-functional co-reactant for polyisocyanates; it could formulate high-solids, two-component polyurethane topcoats, and solvent-free coating materials.
● FEISPARTIC F420 could be a polyurea coating, a chain extender, or an R component. It could also react with –NCO functional HDI trimmer from which a longer gelling time and excellent yellow resistance can be achieved. Longer gelling time can also be obtained when reacting with MDI pre-polymer. A hybrid polyurea and polyurethane can be completed when FEISPARTIC F420 is blended with a hydroxyl-functional resin such as acrylic and alkyd resin; FEISPARTIC F420 offers higher solid content and faster drying time than ordinary polyurethane. It is widely applied in formulating a variety of protective coatings.
● Main Feature
1. High solid content with low viscosity
2. Faster curing time in the aliphatic system
3. Offering excellent physical properties like high hardness, flexibility, elongation(400%), tear, and tensile strength(25MPa).
4. Great weathering and saline water resistance
