Product Overview

Hydrated Lime Powder is manufactured through a controlled hydration process in which high-quality quicklime (CaO) reacts with water to form calcium hydroxide.

Chemical Reaction:

CaO + H₂O → Ca(OH)₂

The resulting product is a fine white powder with strong alkaline characteristics and excellent chemical reactivity.

Hydrated Lime is widely preferred over many alternative alkaline materials because it provides rapid neutralization, easy handling, and excellent performance in various industrial processes.
