Overview
Ludox HS-30 High pH is an strongly alkaline, aqueous dispersion of silica with an average particle size of 12 nm. LUDOX®HS-30 high pH is notably useful as a binder in precision investment casting applications. It can also be used in coating formulations to improve durability and cohesion. LUDOX® HS-30 high pH also helps to improve soil resistance of anti-soil coatings and stool coatings.
