![]() Hardeners: undergo chemical conversion during the curing process with functional groups of polyester resins providing a cross-linked polymer network. Especially our CRYLCOAT® 2441-2, CRYLCOAT® 2618-3, and CRYLCOAT® 4488-0 resins excel in outdoor durability. The resin design defines the outdoor durability, the curing schedule, as well as the physical and chemical stability of correspondent powder coatings. Resins: predominantly determine coating performance like flexibility, toughness, chemical- and corrosion resistance. allnex as a leading global supplier, offers an advanced portfolio of polyester resins, several hardeners and selected additives. Polyester powder coatings consist of the following materials: resins, hardeners, additives, fillers and pigments. There are no limits to color, gloss level or special effects.Įverything you need for polyester powder coatings Powder coatings allow the application of very high dry film thicknesses in a single application pass, with any over-spray not adhering to the substrate being recollected and re-used.Ĭorrespondent coatings are recognized for having a high degree of flexibility, adhesion, chemical-, humidity- and corrosion resistance.Ī right choice of coating ingredients allows the formulation of coatings providing outstanding durability on exposure to aggressive environments. ![]() ![]() Powder coatings are solvent-free during all stages of processing, including application and curing and are commonly regarded as low or zero VOC systems. Powder coatings offer several advantages over conventional coatings systems: The technical and commercial breakthrough was achieved by combining polyester resins with solid epoxy resins in so-called hybrid powders for indoor use other UV resistant curing agents allow the formulations of powder coatings with outstanding outdoor durability for many applications.
