2.Properties and application
●FEISPARTIC F420 is an amino-functional co-reactant for polyisocyanates and could be used to formulate high-solids, two-component polyurethane topcoats, and solvent-free coating materials. It’s the same model as NH1420
● FEISPARTIC F420 could serve as a polyurea coating chain extender or 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. Hybrid polyurea and polyurethane can be completed when FEISPARTIC F420 is blended with a hydroxyl-functional resin such as acrylic or 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.
