Calcium Chloride
Calcium Chloride is an inorganic salt composed of calcium and chlorine with the chemical formula CaClâ‚‚. It typically appears as a white crystalline solid or granular powder, highly soluble in water and exhibiting strong hygroscopic properties. Calcium Chloride is widely used for its moisture-absorbing ability, de-icing, dust control, and as a firming agent in food processing. It finds extensive applications across industrial, pharmaceutical, agricultural, and food sectors due to its efficacy in modifying physical and chemical properties of products and environments.
Calcium Nitrate
Calcium Nitrate is a highly soluble, white crystalline salt composed of calcium and nitrate ions. It is commonly available as a tetrahydrate (Ca(NO₃)₂·4H₂O). Known for its excellent solubility in water, calcium nitrate is widely used as a fertilizer providing both calcium and nitrogen to plants. It improves soil structure, enhances nutrient uptake, and prevents disorders such as blossom-end rot in fruits. Beyond agriculture, calcium nitrate serves in wastewater treatment, concrete acceleration, and industrial chemical processes.
Calcium Nitrite
Calcium Nitrite is an inorganic compound commonly supplied as a white crystalline powder or granules. It serves primarily as a corrosion inhibitor in reinforced concrete structures, protecting steel reinforcement from rust and prolonging structural lifespan. Calcium nitrite is also used in various industrial processes as an oxidizing agent and preservative. Due to its high solubility in water and strong oxidizing properties, it effectively prevents chloride-induced corrosion and improves concrete durability.

Caustic Soda Flakes, also known as Sodium Hydroxide Flakes (NaOH), are a highly alkaline, white, solid substance that is crystalline and flaky in form. Produced by evaporating aqueous sodium hydroxide solutions, these flakes are highly soluble in water and exhibit strong corrosive properties. Caustic Soda Flakes are widely used in a variety of industrial, chemical, and manufacturing processes due to their strong alkalinity, ability to saponify fats, and effectiveness in pH adjustment. Their high purity and ease of handling in flake form make them suitable for use in chemical synthesis, pulp and paper production, water treatment, and detergent manufacturing.
Corn Starch Industrial Grade
Corn Starch Industrial Grade is a finely milled, white powder derived from the endosperm of maize (Zea mays). Unlike food-grade starch, industrial grade is tailored for non-food applications where its thickening, adhesive, and film-forming properties are exploited. It consists primarily of amylose and amylopectin polysaccharides and is valued for its biodegradability, renewability, and cost-effectiveness. Industrial corn starch is used extensively as a raw material or functional additive across a wide variety of manufacturing processes, including paper, textiles, adhesives, and packaging industries.
Master Air
Master Air is a high-performance air release agent used primarily in concrete and construction applications. It facilitates the release of entrapped air bubbles from fresh concrete mixtures, improving workability, surface finish, and durability. This additive enhances the homogeneity of concrete by reducing air voids that can weaken the structure. Master Air is suitable for use in ready-mix concrete, precast elements, and other cementitious materials, contributing to improved mechanical properties and longevity of the final product.
Master Cast
Master Cast is a high-quality gypsum-based casting material designed for producing precise and durable molds, prototypes, and decorative castings. It offers excellent flowability, rapid setting time, and high strength after curing. Master Cast is widely used in ceramics, sculpture, dentistry, and industrial mold-making applications where fine detail reproduction and surface smoothness are critical.
