Overview
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.

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.
