Ask Joe Powder
"In polyester/TGIC systems, the Tg is sensitive. Every weight percentage of TGIC reduces the Tg by approximately 1.5 to 2ºC. Why does TGIC reduce the Tg of the coatings? My idea is that TGIC has a very low equivalent weight, and therefore a low crosslinking density. Generally, low equivalent weight hardeners reduce the Tg. The same thing happens with polyester/Powderlink 1174, which also has a low equivalent weight. But this effect does not occur with polyester/hydroxyalkyl amide systems. Why?"
