Columbia Coatings For Powder Painting

Recommended Posts

So who knows what TGIC means on some of their colors?

Copied and pasted from a Google search.

TGIC (triglycidyl isocyanurate).

TGIC is a low-molecular-weight, multifunctional crosslinker which enables polyester TGIC formulations to contain 90% or greater resin within the binder system. Because they enhance the weather-resistance of polyester, TGIC coatings are comparable to polyester urethane coatings. They also offer faster or lower temperature curing than polyurethanes, and unlike urethane coatings, TGICs maintain excellent mechanical properties at film builds above 3 mils – with no outgassing. Additionally, TGIC coatings provide superior coverage of sharp edges – that’s important in the manufacture of computer components. Sounds good right?

So what’s wrong with TGIC? It nicely enhances the coatings and improves coverage. The issue is that it is TOXIC. TGIC is a Category 2 mutagen. As a result it is now classified as a toxin and cannot be used in certain regions. TGIC is known to cause skin sensitization in some people, which can lead to severe skin rashes. Respiratory sensitization is also a concern.

Exposure occurs by breathing in dust containing TGIC, by skin contact and by ingestion. Ingestion can be caused by contamination of hands, food and drink, and following inhalation. As a result beginning this year many companies in the European Union have stopped applying this material, and this practice will propagate to other regions as well.

Not trying to be an alarmist here at all. As a matter of fact, in the small quantities and just heat and dip like we do, I think this risk is minimal. Just don't eat the stuff. If you were spraying and painting electrostatically, there might be some issues here and precautions taken.
