High permeability epoxy resin chemical grouting material
Characteristics and instructions：
Guangzhou Institute of Chemistry, Chinese Academy of Sciences is the first chemical grouting materials and technology research unit, has successfully developed three generations of high permeability epoxy chemical grouting material: The series of 798,400 and YDS series. The product has been widely used in low permeability weak domestic large-scale hydroelectric dams basis situ reinforced concrete defect treatment and processing.

Features:
1. Initial low viscosity, penetration particularly strong, high mechanical properties of the consolidation, the gelling time can be adjusted, in the presence of water use;
2. On-site preparation is simple to use, single perfusion
3. Consolidation body non-toxic, no environmental pollution
4. Excellent Weather resistance and durability.
Applications:
1. low permeability weak foundation reinforcement situ consolidation process;
2. reinforced concrete cracks especially fine crack reinforcement;
3. A variety of piping materials and contact with the concrete surface against leakage;
4. Anti-acid, anti-alkali, anti-salt, anti-corrosion urea concrete and metal surfaces.
