Substance Name: Aquafil
RN: 112945-52-5


  • A luting cement.
  • Synthetic amorphous silica (silicon dioxide) is produced by a vapor phase hydrolysis process using chlorosilanes or substituted silanes such as, silicon tetrachloride in a flame of hydrogen and oxygen. This material is formed and collected in a dry state. This product contains no detectable crystalline silica.
