Solvent-borne, Speciality Additive, Wetting & Levelling Agent

VP 7354 Acrylate Levelling agent

The 7354 Acrylate Levelling Agent is a high-performance, non-silicone surface additive specifically engineered for solvent-borne and solvent-free coating systems. Composed of a specialized polyacrylate polymer, this agent functions by reducing surface tension gradients within the liquid film during the drying and curing process. Its primary mechanism involves migrating to the air-liquid interface to provide a uniform surface energy profile, which effectively eliminates common surface defects such as orange peel, pinholes, and craters. Unlike silicone-based additives, the 7354 variant maintains excellent inter-coat adhesion and does not induce foam stabilization, making it ideal for multi-layer coating applications. It is particularly valued in high-gloss topcoats where optical clarity and long-wave leveling are critical parameters. Furthermore, its chemical stability ensures consistent performance across various resin chemistries including epoxies, polyurethanes, and polyesters. By optimizing the rheological flow of the coating, 7354 ensures a smooth, mirror-like finish, enhancing both the aesthetic appeal and the protective integrity.

Attributes

Key Features and Benefits

Superior leveling properties that effectively eliminate orange peel and surface irregularities in high-solids systems.
Non-silicone composition ensures zero risk of inter-coat adhesion failure or contamination in sensitive production environments.
Minimal impact on surface slip, preserving the natural feel of the coating while improving overall film gloss.
Exceptional compatibility with a wide range of polar and non-polar resins, including acrylics and epoxies.
Low tendency to stabilize foam, reducing the need for aggressive defoamers during the high-speed application process.
Provides consistent performance in clearcoats by maintaining high transparency and preventing haze or turbidity during the curing phase within industrial coat finishing cycles.
