CON-AID ASIA

CON - AID ASIA : Technical

CON-AID has the properties of a surfactant or surface agent. It transforms the hydrophilic (attraction of water) nature of the clayey material into hydrophobic (rejection of water) nature as illustrated in Figure 1. The product is effective on soil particles that exhibit significant surface charges, such as clay particles with large specific areas. The reaction of CON-AID on clay particles is relatively simple and effective; the goal is to coat the clay particles with the water repellent sulfonated oil. Since the surface of clay particle is often carrying some ion charges, which has the tendency of attracting free ions to the surface, CON-AID stabilizer is specifically made to replace these free ions. The sequence of reaction is as follows:

The acid of the stabilizer helps to remove free ions from the clay surfaces;
The ionic charge sulfonated oil molecules are then attracted to the clay surface because of the ion charge deficiency of the clay particles. Since the sulfonated oil, like any oil-based product, has water repellent properties, it helps to reduce reabsoption of water or surface tension.
