2 LBS Blue Indicating Silica Gel Desiccant Beads, Industry Standard 3-5mm Reusable Desiccant, for 3D Printer Electronics Camera Jewelry Paintings

Desiccant Beads Size: 3-5mm industrial standard blue silica gel beads with strong hygroscopic property, absorbing up to 35% of their weight in ambient moisture to keep items dry. As premium desiccant beads, they protect valuables dependably.
Color Indication Feature: Blue indicating silica gel turns pink when it absorbs moisture; the color shift serves as a clear reminder of its working status. Initial color change doesn't mean depletion, so you can continue using it until fully saturated.
Reusable & Reactivatable: This cobalt chloride-free silica gel changes color from blue to pink when saturated. Once fully pink, it can be reactivated for repeated use.
Oven recommended: spread beads in a single layer and bake at 176248°F (80120°C) for 12 hours until back to blue.
Microwave for small batches only: heat at 30%50% power in 35 minute cycles, stir until fully blue. Do not exceed 300°F (150°C) or use full high power to avoid damage. Ideal for home, workshop and industrial moisture control.
Packaging & Easy Use: 2 LBS silica gel desiccant beads come in heavy-duty double-sealed airtight barrel to avoid premature moisture absorption; ideal for deploying desiccant for 3D printer and large-scale storage.
Wide Applications: Versatile desiccant beads fit for large-scale protection of 3D printer filament (prevents clogs), electronics, camera, jewelry, paintings and air compressors; this silica gel desiccant delivers all-around humidity defense for home, workshop and industrial use.
Important Safety Notice: This blue silica gel contains 0.3 % cobalt chloride; large ingestion may pose health risks. DO NOT use for food or medication purposes, and keep away from children and pets
