TOT is ideal not only for preserving archaeological sites but also for preserving earthquake faults!

TOT is a solution of alkoxides containing silicon, to which a solvent such as ethyl alcohol is added, and this alkoxide solution is subjected to hydrolysis and polycondensation. By applying, spraying, or impregnating this agent solution onto the object to be preserved or reinforced, the agent polymerizes and solidifies between the particles of the object, thereby improving its strength. Unlike the polymer resin-based agents that have been used so far, it has good permeability and dries quickly. Additionally, since the material used is silicon (Si), it easily blends with the original soil components, making it a natural and environmentally friendly agent. Furthermore, it does not use ketones, which have been commonly used as solvents in previous preservatives, and instead uses ethyl alcohol, making it a clean material type of reinforcement preservative that is friendly to both humans and the environment.

basic information

**Features** ○ Increased weather resistance outdoors, able to withstand weathering In outdoor weathering experiments, three types of treatments were conducted, and the progress of weather resistance was observed. Untreated soil was completely washed away in just a few weeks due to wind and rain, while the soil treated with TOT (impregnation treatment) maintained its original shape even after more than six months. The soil with surface treatment lost some of its internal soil because the TOT only penetrated the surface. ○ Color tone and texture remain unchanged after treatment For the treatment of tuff, conventional products tend to darken somewhat, but with TOT, there is almost no change. Additionally, it does not form a film on the surface or create a glossy appearance. ○ Increased surface hardness Reinforcement treatment was applied to medieval tiles. The surface hardness (Hv) was evaluated using the Vickers hardness test, a type of indentation hardness test, and it increased approximately four times compared to untreated samples. Furthermore, the water absorption rate in stone materials is low, resulting in higher durability against weathering. ● For more details, please contact us or download the catalog.
