Everything you need for polyester powder coatings
Polyester powder coatings consist of the following materials: resins, hardeners, additives, fillers and pigments. allnex as a leading global supplier, offers an advanced portfolio of polyester resins, several hardeners and selected additives.
Resins: predominantly determine coating performance like flexibility, toughness, chemical- and corrosion resistance. The resin design defines the outdoor durability, the curing schedule, as well as the physical and chemical stability of correspondent powder coatings. Especially our CRYLCOAT® 2441-2, CRYLCOAT® 2618-3, and CRYLCOAT® 4488-0 resins excel in outdoor durability.
Hardeners: undergo chemical conversion during the curing process with functional groups of polyester resins providing a cross-linked polymer network. The allnex line of poly-anhydride hardeners like ADDITOL® P 791 and BECKOPOX™ EH 694 serve as specialties in specific coatings segments.
Additives: every powder coatings formulation requires the presence of certain additives to optimize characteristics such as: flow and leveling, to avoid film defects like craters and fish-eyes, triggering reactivity and chargeability for tribo applications. Some additives are essential to enhance smoothness and flexibility of coatings or to enable formulation of effect coatings leading to wrinkle finishes.
