Properties and Uses
N,N,N’,N’-Tetrakis (β-hydroxyethy) Adipamide HH8080/HH8081 is a white solid.
In granular form, N,N,N’,N’-Tetrakis (β-hydroxyethy) Adipamide HH8080/HH8081 is commonly used as a hardener in weather-resistant powder coatings based on polyester resins.
N,N,N’,N’-Tetrakis (β-hydroxyethy) Adipamide HH8080/HH8081 serves as a replacement for triglycidyl isocyanurate , which is rarely used in Europe due to its labeling requirements.
Powder coatings crosslinked with hydroxylalkylamides, based on carboxyl-containing polyester resins, are characterized by good weather resistance.
The hydroxylalkylamide reacts with the carboxyl groups of the polyester resin via a polycondensation reaction , producing byproducts.
These byproducts are mainly water and a small proportion of lower alcohols.
The resulting network makes the powder coating highly resistant to aggressive ultraviolet radiation.
At the same time, hydroxylalkylamide-crosslinked powder coatings exhibit good flexibility with comparatively satisfactory chemical resistance, similar to TGIC-crosslinked systems.
