VP 7356 Surface Enhancement Levelling agent

Name: VP 7356 Surface Enhancement Levelling agent - Vortex
SKU: 7356

The 7356 Surface Enhancement Levelling Agent represents a state-of-the-art solution specifically engineered to optimize the surface characteristics of industrial coatings, inks, and resins. Formulated as a high-molecular-weight polyacrylate copolymer, this additive functions by effectively reducing the interfacial tension between the liquid coating and the substrate. Its primary objective is to facilitate uniform wetting while suppressing common surface defects such as orange peel, cratering, and pinholes. Unlike silicone-based alternatives, the 7356 variant provides superior leveling performance without compromising inter-coat adhesion or inducing recoatability issues. It is particularly effective in high-solids solvent-borne systems, where viscosity control and flow dynamics are critical for achieving a mirror-like finish. By stabilizing the liquid film during the evaporation and curing phases, 7356 ensures a consistent, high-gloss topography. Its robust chemical architecture makes it compatible with a wide range of resin chemistries, including epoxies, polyurethanes, and polyesters, making it an indispensable component for demanding industrial coating applications.
