Polyester coating powders

As a not or low toxic polyester curing agent, primid has been introduced in recent years. Is there any difference between mechanical and chemical resistances or finishing properties of coatings made by primid in comparison with TGIC? Which one is better? Leila Manshoori

Hi Leila,

In terms of performance TGIC cured powders have slightly better durability and mechanicals. But this product is classified as toxic, irritant and a mutagen. "Primid" cured powders are much safer to use, and give sufficient degrees of durability and mechanical properties.

Hope this helps,
