The silica dispersion is sodium stabilized and theamorphous silica particles carry a negative surface charge. TheSiO2 particles are discrete, have a slightly rough, sphericalshape, and are present in a narrow particle size distribution. Thephysical appearance of the dispersion is a translucent liquid,slightly more viscous than water. GT-50 is produced for world-wideditribution.Typical PropertiesSilica, wt%:                  25pH:                          11Viscosity,mPa.s:              12Particle Size, nm:            22Density, g/cm3:               1.18Na2O, wt%:                    0.55Range of ApplicationsGT-50 is a versatile product thathas many different application and functions.Storage, Handling, & TransportGT-50 should be transported andstored at a temperature of 5-35℃(40-95oF). If the silica dispersionis allowed to freeze, the silica will irreversably precipitate. Forbulk storage, the tank should be sealed and constructed of plastic,fiberglass reinforced plastic, or stainless steel. For packagedgoods, any translucent packages should be stored out of directsunlight or bright light. Under recommended conditions, GT-50 has ashelf life of at least twelve months after production.GT-50 is available in bulk andpackaged Bulk shipping and packaging sizes can vary byregion.Before handling this material,review the corresponding Material Safety Data Sheet. 欢迎新老客户惠顾，量大优惠！免费提供样品，咨询电话：020-82726119
