Covestro Desmodur® Z 4470 MPA/X Polyurethane
Categories:	Polymer; Thermoset; Polyurethane, TS
Material Notes:	Characterization: Aliphatic polyisocyanate (IPDI trimer). As the hardener component for lightfast polyurethane coating systems and as an additive resin for alkyd spray coatings. Properties / Applications: Desmodur® Z 4470 MPA/X is used primarily as the hardener component for lightfast two-component polyurethane coatings with high resistance to chemicals and weathering, very good gloss retention and outstanding mechanical properties. On account of its high hardness, Desmodur® Z 4470 MPA/X is normally mixed with Desmodur® N products. Preferred co-reactants are flexibilised polyacrylate polyols such as Desmophen® A 565 and A 575 and polyester polyols such as Desmophen® 670. The main applications for two-component coatings based on Desmodur® Z 4470 MPA/X are in automotive OEM and automotive refinishing. As Desmodur® Z 4470 MPA/X has very good physical drying properties, it is also used as an additive resin in alkyd spray coatings to accelerate drying. The main applications of such coatings are in automotive refinishing and industrial finishing. Information provided by Covestro
