TC 720 Colloidal Silica

TC 720 is a "one component" injection system, based on a nanometric Colloidal Silica suspension. The open time can be adjusted with an accelerator. The product may be used between +5°C and +40°C and contains neither solvents nor toxic components. The gel time may be adjusted by varying the quantity of Accelerator for TC 720 added to Component A. Due to the hydrophilic nature of the product, the adhesion is also good to wet surfaces. There is no foam reaction that can negatively influence the bond. Equipment can easily be cleaned using water.
