About Calcium Hydroxide (Hydrated Lime) Grade

Calcium hydroxide, commonly referred to as hydrated lime, is an essential chemical widely employed in various industrial processes. It appears as a white powder or fine granules and is primarily used for pH adjustment, water softening, and as a neutralizing agent. The product is typically supplied in 25 kg bags, suited for efficient transportation and storage. Finstar Chemicals supplies hydrated lime to industrial buyers across the East African region, including Kenya, ensuring reliable and timely deliveries to support critical operations. In water treatment, calcium hydroxide helps precipitate hardness-causing ions, improving water quality and protecting downstream equipment. It is also integral in construction for soil stabilization, mortar, and plaster formulations, where it enhances strength and durability by chemically interacting with silicates in cementitious materials. Agriculture leverages hydrated lime to amend acidic soils, improving nutrient availability and crop yields. Handling requires proper protective equipment due to its alkaline nature, and storage should be in dry, well-ventilated environments to prevent caking and degradation. Procurement teams benefit from consistent packing standards (commonly 25 kg sacks), enabling streamlined logistics and inventory control. Finstar Chemicals provides full compliance documentation and batch traceability to support industrial quality assurance and regulatory needs. Selecting the appropriate grade and maintaining controlled moisture levels are vital to optimize performance across applications. Substituting other lime products can alter reaction rates and end-use properties, so buyers should consult with technical representatives for tailored recommendations. Finstar's support extends to application guidelines and technical advice, making hydrated lime a dependable choice for industrial processes requiring effective alkalinity and soil conditioning agents.
