Hydrated Lime (or calcium hydroxide, or slaked lime) is usually a dry powder resulting from the controlled slaking of quicklime with water. The exothermic or released heat of reaction is captured and used to evaporate the excess slaking water.

Chemical formula: Ca(OH)2 

Chemical composition of Hydrated Lime available in each grade.

Hydrated Lime having higher percentage of Calcium Hydroxide ( 90%) over low grade (65% Purity) Hydrated Lime

Specifications:

Reduced reaction time: The rate of chemical reaction depends upon the degree of purity of the Chemical being used. Higher the purity, lesser would be the reaction time.
Reduced consumption: By Quantitative Analysis it is established that 1 mt. of 90% grade Hydrated Lime is equivalent to 1.378 mt. of 65% purity Grade. Thus there is a reduction of 37.8% in consumption.
