Acrylic Leveling Agent
CAS Number: 25035-69-2
Low-molecular-weight acrylic copolymer leveling agent that improves surface smoothness and gloss in solvent-borne and UV-curable coatings while maintaining excellent intercoat adhesion. It reduces surface tension gradients during film formation without migrating excessively to the surface. Particularly effective in high-bake industrial enamels and powder coating systems.
