Silica Gel Self-Indicating / Desiccant

Silica Gel Self-Indicating (Blue)
6–20 Mesh

PRODUCT DESCRIPTION
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Self-indicating silica gel is a premium moisture-adsorbing desiccant designed for efficient humidity control in laboratory, industrial, pharmaceutical, electronic, and storage applications. The material contains moisture indicator compounds that visually signal saturation through color change.

This grade is supplied in coarse 6–20 mesh particle size for enhanced airflow, durability, and moisture adsorption efficiency.

The blue indicating form typically changes from deep blue to pink/purple upon moisture absorption, signaling regeneration or replacement requirement.
