Flow Agent
CAS Number: 556-67-2
Silicone-based flow agent used in powder coatings and liquid coating systems to improve flow, leveling, and surface smoothness during the cure cycle. It reduces melt viscosity and surface tension, allowing the coating to flow out uniformly before gelation. Provides excellent film smoothness without negative effects on adhesion or recoatability.
