Self-indicating silica gel is a moisture-absorbing desiccant featuring color-changing properties to signal its saturation level. Unlike standard silica gel, it incorporates cobalt chloride or other moisture-sensitive indicators that shift in color, typically from orange to green or blue to pink, when maximum absorption capacity is reached.
This innovative gel is widely employed in industries such as electronics, pharmaceuticals, and archival storage to protect against moisture-induced damage like mold, rust, and degradation. Its color-changing feature provides a visual cue for timely replacement or reactivation, ensuring continuous and effective humidity control without the need for external humidity sensors or equipment.
