Solvent-borne, Speciality Additive, Wetting & Levelling Agent

VP 7410 Anti Stick Levelling agent

Name: VP 7410 Anti Stick Levelling agent - Vortex
SKU: 7410

The 7410 Anti-Stick Leveling Agent is a high-performance, silicone-based additive engineered to optimize surface characteristics in coating systems. Formulated as a polyether-modified polysiloxane, this specialized agent drastically reduces surface tension, facilitating superior substrate wetting and eliminating common surface defects like orange peel, craters, and pinholes. Its unique molecular architecture provides a balanced ratio of compatibility and surface activity, ensuring a smooth, mirror-like finish across various resin systems, including solvent-borne, water-borne, and UV-curable formulations. Beyond aesthetic enhancement, 7410 introduces a strategic “anti-stick” functionality, which significantly lowers the coefficient of friction (COF). This result increases slip resistance, enhances mar and scratch durability, and prevents substrate blocking during stacking or processing. Designed for low-dosage efficacy, it serves as a critical component in high-end industrial coatings, wood finishes, and printing inks where surface slip and optical clarity are paramount. 7410 remains a benchmark for precision leveling and surface protection in modern chemical engineering applications.

Attributes
