The stability of powder coatings are powder during storage or whether the occurrence of powder agglomeration in use, flow characteristics of variation,charged effect is poor, the film orange peel was weakened, gloss, pinhole bubble generation etc..Pigment Carbon Black
In the production of powder coatings, attention must be paid to its storagestability, only with a certain stability of powder coating, can let the users. Abroad,often adding some additives in powder coatings, powder coatings to enhance the stability, so this kind of powder coatings in general in the damp or high temperature 70-75 ℃ also won't produce agglomerate.
The stability of Powder Coatings powder coating is used at a certain temperature, the flow changes to determine treatment after a certain period of time. Because of the stability of Powder Coatings powder coating in the storageconditions and the molecular cross-linking degree of crosslinking reactionoccurred; powder more intense, the molecular weight of powder, as reflected in the powder in the curing temperature viscosity, and flow characteristics of variation.Carbon Black Pigment
