Leveling Agent Working Mechanism and Chemi Tech Product Analysis

As critical additives in coating systems, leveling agents function through precise regulation of liquid surface tension and flow behavior. Chemi Tech leveling agents employ unique chemical structure designs to achieve dynamic surface tension balance during coating curing, effectively eliminating surface defects like orange peel and cratering.

The working mechanism of Chemi Tech leveling agents encompasses three core functions:

Surface tension gradient elimination: Migrate to coating surface to reduce local tension differences

Flow process optimization: Adjust system viscoelasticity to extend open time for complete leveling

Interface defect repair: Selective adsorption on substrate micro-cavities improves wettability

Chemi Tech's modified polysiloxane technology ensures stable compatibility across various resin systems. Functional groups in molecular chains dynamically rearrange during curing: rapid migration to interfaces during initial stage, maintaining fluidity at mid-stage, and achieving ordered alignment at film-forming stage without compromising gloss or adhesion.

For high-solid systems, Chemi Tech developed gradient-surface-activity leveling agents. Multi-functional groups create tension gradients through coating thickness, driving fluid flow from high-tension to low-tension zones, particularly effective for vertical spraying. Lab tests show 0.3%-0.8% dosage reduces surface roughness by 62% and enhances gloss by 35%.
