GT-30is an alkaline, aqueous dispersion of colloidal silica thatis approximately 30% solids by weight. The silica dispersion issodium stabilized and the amorphous silica particles carry anegative surface charge. The SiO2particles are discrete, have aslightly rough, spherical shape, and are present in a narrowparticle size distribution. The physical appearance of thedispersion is a translucent liquid, slightly more viscous thanwater. GT-30 is produced for world-wide ditribution.

Range of Applications

GT-30 is a versatile product that has many different applicationand functions.

Storage, Handling, & Transport

GT-30 should be transported and stored at a temperature of5-35℃(40-95oF). If the silica dispersion is allowed to freeze, thesilica will irreversably precipitate. For bulk storage, the tankshould be sealed and constructed of plastic, fiberglass reinforcedplastic, or stainless steel. For packaged goods, any translucentpackages should be stored out of direct sunlight or bright light.Under recommended conditions, GT-30 has a shelf life of at leasttwelve months after production.

GT-30 is available in bulk and packaged quantities. Bulkshipping and packaging sizes can vary by region.

Before handling this material, review the corresponding MaterialSafety Data Sheet.
