LUDOX® HS-40-FS, 38% Silica
LUDOX® HS-40 is a freeze thaw stable colloidal silica with a particle size of 12 nanometers that is used as a binder for coatings and refractory materials.
LUDOX® HS-40 is an alkaline, aqueous dispersion of 12 nanometer silica. It contains 38% solids and is freeze thaw stabilized with ethylene glycol.
Because of the freeze thaw stability, LUDOX® HS-40 FS is suited for cold weather climates and situations where temperature controlled storage is not available.
Specifications
Density (g/cm³, lb/gal): 1.3, 10.8 Boiling Point (760 mm Hg) °C/°F: 100/212 Melting Point °C/°F: 0/32 Vapor Pressure (25°C) mm Hg: 24 Vapor Pressure (38°C) mm Hg: 48 Stabilizing Counter Ion: Sodium Particle Charge: Negative Biocide ppm: 240
Primary Chemistry: Colloidal Silica
Features & Benefits
Small particle size Narrow particle size distribution High thermal stability Freeze / thaw stable Excellent binders Adhesion promoters Anti-slip properties Anti-blocking agents Soil retardants Reinforcing agents for improved resistance Improved polishing performance
Problems Solved
Accidental freezing of LUDOX® HS-40 during storage or use in cold weather climates. Low cohesive strength of coatings and adhesives that lead to structural failure.
Applications
LUDOX® HS-40 FS is primarily used as a high stability binder for refractory fibers used in high temperature applications.
In water-based coatings and adhesives LUDOX® HS-40 FS works to improve durability and cohesion of the system by becoming an integral part of the polymer matrix and latex film. LUDOX HS® HS-40 FS can also be used as an adhesion promoter for inorganic surfaces like metal and glass.
