Product Description
M-43 is a four-functional N,N,N',N'-tetrakis(2-hydroxypropyl)adipamide compound with excellent color stability, compared with Traditional N,N,N,N-tetrakis(2-hydroxyethyl)adipamide, the anti-yellowing performance is significantly improved, especially under the condition of curing after gas baking, it is especially suitable for applications with high requirements and high color stability, and can be used with carboxyl polyester resins cross-linking to produce non-toxic, non-irritating outdoor weather-resistant powder coatings.
