7380 is a high-performance, non-silicone, and fluorine-free levelling agent specifically engineered for advanced coating systems requiring superior surface aesthetics without the traditional risks …
Fluorine-Free Compliance: Eliminates PFAS-related regulatory concerns, aligning with global green chemistry initiatives for sustainable manufacturing.
Non-Silicone Chemistry: Guarantees zero silicone oil contamination, preventing common defects like “fish-eyes” and ensuring excellent intercoat adhesion.
Enhanced Recoatability: Facilitates superior bonding for subsequent coating layers without the need for intensive surface preparation or sanding.
Optimal Surface Levelling: Dramatically reduces orange peel and surface roughness, resulting in a high-gloss, mirror-like finish across various applications.
Versatile Compatibility: Demonstrates broad solubility and efficacy in solvent-borne, water-borne, and UV-curable systems, providing formulation flexibility for diverse industrial requirements and stable storage life under varying environmental conditions for prolonged utility.
