Aluminum alloy powder coating: requirements for improving leveling performance

Date: 2021-01-11

Aluminum alloy powder coating has become one of the environmentally friendly coating fragments, which comes from the leveling performance of aluminum alloy powder coating. It refers to the smooth and lubricating form of the coating after application. A surface with good leveling performance should not have irregular shapes such as orange peel, brush marks, ripples, shrinkage holes, etc


So it's here to influence aluminum alloy powder coatings

As for the elements of leveling, one is leveling agents. Adding appropriate leveling agents to the formula of aluminum alloy powder coatings can quickly reduce the surface tension of the coating after melting, promote the rapid movement of the coating before solidification and film formation, and eliminate or add surface defects such as orange peel, brush marks, ripples, shrinkage holes, etc


The second is aluminum alloy powder coating

Melt viscosity refers to the phenomenon in thermosetting aluminum alloy powder coatings where, during the melting process, cross-linking and solidification reactions occur. The higher the temperature, the faster the solidification reaction, resulting in a faster increase in fragmented viscosity, longer activity time, and limited leveling properties
