Application Characteristics of Chemi Tech Leveling Agents in Various Systems

Chemi Tech leveling agents demonstrate exceptional adaptability across coating systems through innovative molecular design. Tailored solutions are achieved via functional group modification and precise molecular weight control.

In solvent-based systems:

Branched polyacrylate structures show excellent compatibility with acrylic/epoxy resins. Hydrophobic chains reduce static surface tension (22-25mN/m), while polar groups form hydrogen bonds with resins to prevent adhesion loss. Particularly suitable for automotive OEM coatings requiring leveling in 80-120μm wet films.

Waterborne system performance:

Self-emulsifying groups form stable micelles. Dual-phase "wetting-leveling" mechanism: initial water/substrate tension reduction (≤40mN/m), followed by drying process control. Maintains stability at pH8-10 with various waterborne PU/acrylic emulsions.

UV system optimization:

Low-migration reactive leveling agents contain polymerizable double bonds. Participate in UV curing with <0.1% residue, solving hardness reduction issues. Photoinitiator synergy ensures 93% surface smoothness under 300-400nm irradiation.
