Infiltration is the use of an infiltration agent, which penetrates into the slits of materials and equipment by natural infiltration, vacuuming and pressurization, fills the slits, and then passes the gaps in the natural (room temperature), cooling or heating methods. The sealing medium is solidified to achieve a sealing gap. Among the commonly used infiltrants, there are two kinds of organic infiltrant and inorganic infiltrant. This article introduces each of these two infiltrants to give you an understanding.

The first use of inorganic impregnation agent for infiltration treatment (Metal Impregnation), and later developed an organic infiltration agent, due to many advantages, many companies use organic infiltration agents instead of inorganic infiltration agents, organic infiltration agents through After 3 upgrades, the 2nd and 3rd generation organic infiltrants are widely used. Due to the poor impregnation effect of the inorganic infiltrant, the use is greatly reduced, but the cost of eliminating the infiltration equipment and the infiltrant is high. Therefore, some enterprises in China and some developing countries still use inorganic infiltration agents, and with the development of social economy, the use of inorganic infiltration agents will be gradually reduced.

Inorganic casting impregnating trapping agent (inorganic casting sealant) is more resistant to heat than organic casting impregnating sealant, so in some cases it is not possible to replace inorganic casting sealant with organic casting impregnating trapping agent. Other informal inscriptions of infiltrants, such as casting trapping agents, casting trapping fluids, etc., because many manufacturers do not come into contact with infiltration and trapping, so there are many other examples such as casting trapping glue, casting sealant, casting sealant, etc.
