Hemispherx Levelol 872 Fluoromodified Leveling Agent – Frequently Asked Questions (FAQ)
Q1: What distinguishes Levelol 872 from conventional silicone-based leveling agents?
A: Levelol 872 is a fluoromodified additive designed to provide superior substrate wetting and flow control in challenging systems where silicones may cause compatibility issues or interfere with overcoating. Its fluorinated structure enhances surface migration efficiency while minimizing defects such as craters, orange peel, and pinholes—particularly in high-solids, low-VOC, or waterborne coatings.
Q2: Is Levelol 872 compatible with waterborne acrylic and polyurethane dispersions?
A: Yes, Levelol 872 demonstrates good compatibility with a broad range of waterborne polymer systems, including acrylics, polyurethanes, and hybrid dispersions. It is formulated to remain stable during storage and resist destabilization during high-shear mixing or extended aging—though compatibility testing under specific formulation conditions is always recommended.
Q3: How should Levelol 872 be incorporated into a coating formulation?
A: It is typically added during the let-down stage, after pigments and primary resins have been dispersed. For optimal performance, incorporate with moderate agitation to ensure uniform distribution without excessive air entrapment. Pre-dilution in a compatible solvent or portion of the vehicle phase may aid dispersion in highly viscous or sensitive systems.
Q4: Does Levelol 872 affect recoatability or adhesion to subsequent layers?
A: Unlike some traditional fluorosurfactants, Levelol 872 is engineered to minimize surface segregation that can impair intercoat adhesion. When used within recommended dosage ranges, it generally supports strong interlayer bonding and does not compromise recoatability in multi-coat architectural, industrial, or protective applications.
