Activated Carbon
Activated carbon is a highly porous form of carbon processed to have a large surface area, making it extremely effective for adsorption. It is widely used to remove impurities, odors, and contaminants from liquids and gases in water treatment, air purification, food processing, and chemical industries.
Ammonium Cupric Chloride
Ammonium Cupric Chloride is a blue-green crystalline inorganic compound composed of copper, ammonium, and chloride ions. It is widely used as a source of copper in agricultural fungicides and bactericides, as well as in electroplating, chemical synthesis, and textile dyeing. Its antimicrobial properties make it valuable for controlling fungal and bacterial infections in plants. Additionally, it serves as a precursor in various industrial and laboratory applications.
Bitumen Primer
Bitumen Primer is a low-viscosity solution of bitumen in organic solvents (e.g., mineral spirits or aromatic hydrocarbons). It is formulated to penetrate porous substrates and enhance adhesion before applying bituminous membranes or coatings. The primer quickly evaporates to leave a tacky, bitumen-rich film that promotes strong bonding. Commonly used in construction, waterproofing, and roofing, bitumen primer improves coating durability, water resistance, and substrate compatibility.
Calcium Carbonate Light
Calcium Carbonate Light is a finely ground, low bulk density natural mineral composed primarily of calcium carbonate (CaCO₃). Compared to standard grades, it has a lower density and larger particle size distribution, making it suitable for applications where light weight and high brightness are important. This form is extensively used as a filler and extender in industries such as plastics, paints, rubber, paper, adhesives, and construction materials to improve opacity, brightness, and texture, while maintaining low weight and cost efficiency. Its chemical inertness and whiteness provide functional and aesthetic advantages across formulations.
Calcium Carbonate uncoated
Calcium Carbonate uncoated is a naturally occurring mineral compound composed primarily of calcium, carbon, and oxygen with the chemical formula CaCO₃. It appears as a fine white powder or granules, widely used as a filler, pigment, and functional additive across various industries. The uncoated form means the calcium carbonate particles are not surface-treated, retaining their natural properties. It is valued for its high brightness, whiteness, and excellent compressibility. Uncoated calcium carbonate is used to enhance opacity, improve processing, and reduce costs in plastics, paints, coatings, adhesives, rubber, paper, and construction materials.
Dichloromethane
Dichloromethane, also known as methylene chloride, is a volatile, colorless liquid with a sweet, chloroform-like odor. It is a chlorinated solvent widely used in industrial, pharmaceutical, and laboratory applications due to its excellent solvent properties, including high volatility, moderate polarity, and low boiling point (about 39.6°C). DCM is prized for its ability to dissolve a wide range of organic compounds, making it ideal for extraction, paint stripping, degreasing, and chemical processing. However, due to health and environmental concerns, its use is regulated and controlled in many countries.
