The 7411 Wetting and Levelling Agent is a high-performance, polyether-modified polysiloxane surfactant specifically engineered to optimize the surface tension of liquid coatings, inks, and adhesive…
Superior Surface Tension Reduction: Effectively lowers the liquid surface tension to ensure optimal wetting on low-energy substrates effectively.
Anti-Cratering Properties: Prevents surface defects like fish-eyes and craters caused by substrate contamination or airborne impurities during application.
Enhanced Surface Slip: Significantly improves the scratch and mar resistance of the dried film, extending the coating’s service life.
Excellent Levelling Performance: Promotes a smooth, mirror-like finish by facilitating rapid de-aeration and flow during application.
Broad System Compatibility: Exhibits exceptional stability in solvent-borne, water-borne, and UV-curable systems without affecting inter-coat adhesion or causing unwanted haze.
规格
技术亮点
Chemical Identity: 7411 is a polyether-modified dimethylpolysiloxane copolymer; note that “7411” is a grade designation, often associated with CAS 134180-76-0.
Active Content: Formulated as a 100% active, non-volatile liquid, ensuring high efficiency at low dosage concentrations.
Dynamic Efficiency: Operates effectively at low concentrations, typically between 0.1% and 1.0% of the total formulation weight.
Thermal Stability: Maintains performance integrity across a wide temperature range during both the curing and application process phases.
Solubility Profile: Fully miscible in most organic solvents and readily dispersible in water-based resin systems with proper high-speed shear.
实际行业应用
应用领域
Automotive OEM and Refinish: Crucial for achieving the high-gloss, defect-free “wet look” required for topcoats and clear coats.
Industrial Wood Coatings: Enhances the wetting of wood pores and prevents crawling on oily or resinous wood surfaces.
Printing Inks: Improves leveling and substrate wetting in flexographic and gravure inks, particularly on plastic films and foils.
Protective Metal Coatings: Provides uniform coverage on metal substrates, ensuring corrosion resistance by eliminating film voids and thin spots.
UV-Curable Systems: Optimized for rapid-cure environments, ensuring the liquid film levels completely before the high-intensity UV exposure begins.
