Anionic Surface Sizing Agent from Weifang Fine Chemicals is a styrene acrylic-based copolymer designed for papermaking applications. The product appears as a white to light brown liquid with a minimum solid content of 25%, a pH range of 2-4, and a viscosity of 50 cps maximum at 25°C. It is formulated to cross-link with starch, enhancing water resistance and ring-crush strength in paper.
This sizing agent is synthesized via copolymerization of styrene and ester, offering efficient bonding with starch to improve hydrophobic properties. It is typical for surface sizing agents to reduce costs by minimizing internal sizing requirements, and this product competes with BASF 400DS and BASF 8903/8906 in performance. The agent is compatible with anionic and nonionic auxiliaries, including direct dyes and fluorescent whitening agents.
Primarily used in culture paper such as offset printing paper and electro-photographic paper, this agent requires no curing period and can replace internal sizing entirely. It is supplied in 200 kg PP drums or 1000 kg IBC drums, with a shelf life of 6-12 months. Buyers should store it in cool, dry conditions and handle with care to prevent container damage.

Before ordering, verify the solid content and pH range to ensure compatibility with your papermaking process. Confirm that the viscosity of 50 cps max at 25°C meets your application requirements, as this affects the ease of use and uniformity of the sizing agent on the paper.
Logistics should account for the packaging options of 200 kg PP drums or 1000 kg IBC drums. Buyers must confirm Incoterms such as FOB or CIF with the supplier and request lead times for production and shipment from China. Payment terms should also be clarified to avoid delays in delivery.
Upon arrival, inspect the product for its white to light brown appearance and confirm the pH range of 2-4. Request a certificate of analysis (COA) for solid content and viscosity, and check for any container damage. Store the agent in cool, dry conditions to maintain its 6-12 month shelf life.
