Because powder coatings are virtually organic compound (VOC) free, the mass loss during cure coupled with good application techniques - such as maximized first-pass efficiency and reclaiming - can render excellent powder utilization. Clean-up and disposal considerations are less troublesome than those of wet painting.
Recent industry innovations have provided improvements in the standard DuPont® product line. Technological advancements have provided a full compliment of new chemistries, including high temperature resistant, graffiti and out-gas resistant, post-formable, and weatherable wrinkle finish powders. All new DuPont® powder technologies are tested to assure maximum performance consistency upon commercialization. This provision makes DuPont® Alesta Powder Coatings a name that can be trusted.
DuPont®Product Number System
The first letter: Binder Type
E = Epoxy
U = Aliphatic-Urethane (called Urethane)
R = Epoxy Polyester Hybrid
P = TGIC Polyester
A = Aromatic-Urethane
G = Polyester, TMMGU Glycouril curative
S = Siloxane or Silicone-Polyester
The second letter: Cure Response
F = Fast cure. Generally, 10 minutes @ 400°F is sufficient to cure 20-gauge metal and lighter.
L = Low cure. Generally, 10 minutes @ 325°F is sufficient to cure EL and RL products on 20-gauge metal
R = Rationation rather than thermal cure systems
Heavier metals require more time and/or higher temperatures. Properties summarized are typical. Refer to individual product technical data sheets for specific cure information.
The third letter: Color
A = Aluminum or Silver
B = Black
C = Clear
D = Gold, Brass, or Copper
G = Green
H = Gray
J = Brown or Bronze
K = Blue
L = Ivory or Cream
M = Maroon
P = Pink or Purple
R = Red
S = Orange
T = Tan or Beige
W = White
Y = Yellow
