Aojin Chemical is an export supplier of chemical raw materials—specifically Calcium Nitrite, SAF, and SNF—serving the construction chemical and water treatment sectors. Our products are supplied in bulk to meet the diverse procurement needs of factories, traders, and distributors across Southeast Asia, the Middle East, Central Asia, Africa, and Latin America.
1. Calcium Nitrite (CAS: 13780-06-8; HS Code: 28341090; Molecular Formula: Ca(NO₂)₂)
This product offers four core functions: rebar corrosion inhibition, low-temperature antifreeze protection, early strength development for cement, and anti-corrosion/controlled-release properties. In civil engineering projects located in cold regions during winter, adding Calcium Nitrite extends the service life of reinforced concrete structures; it lowers the freezing point of concrete to prevent freeze-thaw cracking while accelerating cement hydration and shortening formwork removal and curing cycles. Additionally, Calcium Nitrite serves as a corrosion inhibitor for lubricants, an intermediate for organic synthesis, a cleaning agent for heavy oil, and an anti-corrosion agent for boiler systems, making it suitable for a wide range of industrial applications.
Target Customers: Concrete admixture blending plants, road and bridge infrastructure contractors, oilfield chemical enterprises, manufacturers of metal anti-corrosion materials, and chemical trading companies.
2. SNF Naphthalene-based High-performance Water Reducer (Sodium Naphthalene Formaldehyde; CAS: 36290-04-7; HS Code: 3824401000)
SNF (naphthalene sulfonate-formaldehyde condensate)—commonly known in the industry as a naphthalene-based high-performance water reducer—is the most versatile anionic high-performance concrete dispersant on the market.
The product demonstrates excellent compatibility with various admixtures, such as Calcium Nitrite, antifreeze agents, and retarders, and is frequently used to formulate all-in-one antifreeze and corrosion-inhibiting admixtures. It is suitable for pumped concrete, precast components, high-strength mortar, grouting materials, and shotcrete for tunnels. It also serves as a dispersant for dyes, a water reducer for ceramic bodies, and a dispersing aid in the rubber industry. Aojin SNF products are available in bulk ton bags or 25kg woven bags.
3. SAF High-Efficiency Dispersant
In industrial applications, SAF is suitable for water-based coatings, refractory materials, gypsum products, and inorganic powder grinding/dispersion systems. It offers high-temperature, acid, and alkali resistance, providing long-lasting dispersion without re-flocculation. It can be combined with calcium nitrite and SNF to form a comprehensive raw material solution.
III. Aojin Chemical’s Core Competitiveness as a Supplier
1. Supply Chain Advantages (Origin-Based)
Maritime shipments are handled via the Port of Qingdao, offering direct routes to major ports in Southeast Asia, the Middle East, and Africa, ensuring high loading efficiency and reliable logistics timelines.
One-stop procurement of the three main materials—combined with the formulation of composite admixtures (antifreeze, early-strength, rust-inhibiting, and high-dispersion types)—minimizes communication and inspection costs associated with sourcing from multiple vendors.
