Additives (e.g., Flow Agents): Density 0.9-1.2 g/cm³

Component Specifications

Definition

Additives such as flow agents are chemical compounds incorporated into powder silicone resin formulations to enhance flowability, reduce agglomeration, improve dispersion, and optimize curing behavior. They are critical for achieving uniform coating, preventing defects, and ensuring consistent mechanical and thermal properties in final products.

Working Principle

Flow agents reduce interparticle friction and surface tension, allowing powder particles to flow freely during application and leveling. They may also act as wetting agents, improving resin-substrate adhesion and promoting uniform film formation.

Materials

Typically organic polymers (e.g., polyacrylates, polyolefins), siloxanes, or modified silicones. Particle size: 1-50 µm. Purity >99%.
