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.
Cellulose Ether
 Cellulose ether refers to a group of chemically modified cellulose derivatives where hydroxyl groups on the cellulose backbone are substituted with ether groups such as methyl, hydroxyethyl, or carboxymethyl groups. These modifications improve solubility, viscosity, and film-forming properties while maintaining biodegradability and non-toxicity. Cellulose ethers are white to off-white powders or granules that dissolve in water to form viscous, stable solutions. They are widely used as thickeners, binders, stabilizers, and film formers in industries such as construction, pharmaceuticals, cosmetics, food, and paper.
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 Fibre
 Master Fibre is a high-quality synthetic fiber additive designed to reinforce concrete and mortar mixtures. It improves structural integrity by enhancing tensile strength, reducing cracking, and increasing durability. The fibers disperse uniformly within the mix, providing better load distribution and impact resistance in industrial, commercial, and residential construction applications. Master Fibre enhances performance without compromising workability, making it ideal for use in concrete slabs, pavements, beams, and repair mortars.
Master Seal 530
 Master Seal 530 is a premium, flexible, cementitious waterproofing slurry designed for protection of concrete and masonry surfaces against water ingress. It offers excellent adhesion, crack bridging, and durability even under severe weather and water exposure conditions. Suitable for use on basements, swimming pools, water tanks, terraces, and retaining walls, Master Seal 530 forms a robust waterproof barrier that resists hydrostatic pressure and prevents moisture damage.
Sika Filler Coarse Surface Filler
Sika Filler Coarse Surface Filler is a high-quality, ready-to-use, cement-based filler designed for repairing and leveling rough, porous, or uneven concrete and masonry surfaces. It offers excellent adhesion, durability, and workability, allowing for quick and easy application on coarse substrates. This filler is suitable for both interior and exterior use, providing a solid base for further finishing or coating. It is ideal for patching large holes, cracks, and damaged surfaces prior to painting or sealing.
Sodium Silicate
Sodium Silicate is a water-soluble, viscous alkaline liquid with the general formula Na₂SiO₃ (ratios vary). Commonly referred to as water glass or liquid glass, it appears as a clear to slightly cloudy solution. This 20-litre packaged product is known for its excellent adhesive, binding, and sealing properties. It is widely used in industrial, construction, detergent, and water treatment applications. Sodium silicate forms a glassy film upon drying and resists high temperatures and chemical attack, making it extremely versatile across many industries.
Tally Oil Acid
Tally Oil Acid is a fatty acid derived from tall oil, a byproduct of the kraft pulping process in the paper industry. It contains a mixture of fatty acids, mainly oleic and linoleic acids, and is used as a raw material in chemical manufacturing, soaps, lubricants, and other industrial applications. The product is valued for its renewable origin and versatile chemical properties.
