The gel is mainly used for absorbing moisture for apparatus, instruments, and equipments in airproof condition to avoid them from rusting, and indicating the environmental relative humidity due to its obvious color change.
The gel is mainly used for indicating desiccant’s absorbing degree and environmental relative humidity by being mixed with common silica gel in proportion. Besides, it is also widely used in precision apparatus, leather, shoes, garment, food, drug and household electric appliance industries as silicon gel desiccant.
