VP 4360 Anti-sinking agent for polyethylene wax

The 4360 Anti-sinking agent is a high-performance rheological additive specifically engineered to stabilize polyethylene (PE) wax dispersions within liquid coating systems. Designed to address the inherent buoyancy and sedimentation challenges of micronized waxes, 4360 functions by establishing a robust three-dimensional network through hydrogen bonding and steric hindrance. This structural framework effectively suspends wax particles, preventing hard-caking and ensuring long-term shelf stability without compromising the desired surface properties of the final film. Primarily utilized in solvent-borne and high-solid systems, this agent facilitates a controlled thixotropic flow, allowing for easy pumpability during manufacturing while providing excellent anti-sagging characteristics during application. By optimizing the spatial distribution of the wax phase, 4360 ensures consistent matting, slip resistance, and mar resistance across the coated substrate. It is characterized by its excellent compatibility with various resins, including alkyds, acrylics, and epoxies, making it a versatile solution for formulators seeking superior rheological control in advanced industrial coatings.
