Introduced in 1990, Primid XL 552 (I) is now an established powder coating curing agent.Typical for its generation of raw materials, I reflects today's concerns for health and the protection of the environment.However ultimately, the longevity of any raw material its determined by its tech. performance.For organic coatings performance will be influenced and measured by a number of different factors.In an extensive test program, the chem. and the primary properties of I-based powder coating formulations are discussed.The results presented demonstrate that I-cured powder coatings possess outstanding attributes that make them suitable for a wide range of applications.
