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.
