The 4330A Anti-sinking agent is a high-performance rheological additive specifically engineered for use in polyethylene (PE) wax dispersions and various liquid coating systems. As a specialized pol…
Superior Suspension: Effectively prevents the gravitational settling of polyethylene wax and heavy pigments, ensuring a uniform mixture.
Thixotropic Efficiency: Provides excellent shear-thinning properties, facilitating easy application while maintaining high-structure integrity during rest.
Syneresis Control: Minimizes oil separation and liquid-phase migration, extending the shelf-life of finished wax dispersions and coatings.
Film Integrity: Maintains the mechanical properties of the coating, such as adhesion and flexibility, without causing yellowing.
Ease of Incorporation: Disperses efficiently under standard high-speed stirring, reducing processing time and energy consumption. It also improves anti-sagging performance on vertical surfaces.

技术亮点
Chemical Composition: Primarily composed of modified polyamide wax. (Note: CAS 4330A is a grade designation; specific chemical components vary by supplier).
Effective Temperature Range: Maintains rheological stability across a broad thermal spectrum, typically from 15°C to 60°C.
Dosage Optimization: Highly active at low concentrations, generally ranging from 0.5% to 2.0% based on total formulation weight.
Compatibility: Demonstrates excellent solubility and performance in non-polar to medium-polar solvent systems, including xylenes, mineral spirits, and acetates.
Particle Size Stability: Does not promote particle agglomeration. Its refractive index is carefully matched to prevent film haze.
