Pwogram apre tretman ki gen kèk òganik pigments négative kapab afekte a ki pi efikas selon ditif a. Nan ka sa yo, tès ak non pigman de menm jan de ka pote siksè. Lè te konn sèvi nan mawonnen revêtements, a entèraksyon moun sa a cationiques ditif ak sitwon atalizè a dwe pran anndan konte. Acides amine bloke gen mwens fèt nan Kiba pase acides gratis oswa époxy bloke acides.

The after-treatment of some organic pigments may negatively affect the efficiency of the additive. In such cases, tests with the untreated pigment of the same type may be successful. When used in coil coatings, the interaction of this cationic additive with the acid catalyst must be taken into account. Amine-blocked acids are less suitable than free acids or epoxy-blocked acids.
