Résumé : |
Low temperature curing powder coatings are receiving increasing attention in the coatings inudstry, to conserve energy and also for heat sensitive substrates. Resin combinations commonly used in powder coatings (poly-ester/TGIC, polyester/Bis-phenol A epoxy, polyester/Bis-(N,N'-dihydroxy) adipamide), display an undesirable phenomenon called "blooming", under specific cure conditions. An understanding of this phenomenon and the probability of the formation of macrocyclic structures , responsible to cause blooming in various polyesters has been provided. The development of a nonblooming polyester resin in which a portion of the neopentyl glycol (NPG) has been substituted with 2-butyl-2-ethyl-1,3-propane diol (BEPD:US Patent 5,880,223, Morton International) is presented. THe use of amorphous nonblooming polyester resin in combination with semicrystalline polyester for low temperature curing powder coatings has been described. |
