Application

ACTIRON® TAB P is a versatile catalyst in powder form specially adapted for epoxy cross-linking mechanism- based powder coating. Therefore ACTIRON® TAB P is particularly recommended for powder coating systems such as: Epoxy/polyester, Epoxy/ Dicyandiamide, Polyester TGIC, Polyester/ PT 910. The use of ACTIRON® TAB P allows reducing significantly the curing temperature of the powder coating to reduce energetic costs or to decrease the curing time improving the productivity. A combination of both effect is also possible.

ACTIRON® ACTIRON® TAB P allow to obtain very high Tg cross-linked systems and therefore, is particularly recommended for the manufacture of super durable coatings. Contrary to Imidazole based catalysts, ACTIRON® TAB P does not influence negatively the yellowing of the coating.

 

Method of Use and Recommended Levels

• ACTIRON® TAB P is supplied as free-flowing powder with uniformly-sized particles. Therefore is very easy to incorporate it in the mixture of powders at the time of pre-homogenization.
• Addition amount: 0,5- 2 % on binder and cross-linker. Due to its great resistance to yellowing, higher amount can be used in order to further reduce curing temperature.
