Construction & real estate›💡Electronic & Electrical›🍎Food & Beverages›🛋️Home furnishing & supplies›⚗️Industrial goods & chemical›🪨Minerals & metals›📦Miscellaneous›The Cationic Surface Sizing Agent from Weifang Fine Chemicals Co, Ltd is a styrene-acrylic ester copolymer designed to combine efficiently with starch, creating a strong cross-linked film on paper surfaces. This agent replaces internal sizing chemicals by delivering hydrophobic properties and water resistance directly at the surface, eliminating the need for a curing period. Its milk white to light brown liquid form allows for easy integration into existing sizing processes.
With a solid content of 30% minimum and a pH of 5 max, the product is formulated for stability in paper mill environments. The viscosity at 25°C is capped at 30 cP, ensuring smooth application without excessive thickening. Typical for surface sizing agents, it is supplied in 200 kg PP drums or 1000 kg IBC drums, with a shelf life of 6 to 12 months when stored in cool, dry conditions.
This agent is used primarily in the production of board paper and corrugated paper, where it significantly improves ring-crush strength and water resistance. Paper mills adopt it to reduce sizing costs by lowering dosage requirements, with typical usage rates of 1 to 2 kg per ton of paper. The product is added to cooked starch at 70 to 75°C, with alum used to adjust pH to 3.5 to 4.0 before metering into the size press.

Before placing an order with Weifang Fine Chemicals Co, Ltd, confirm the exact solid content, pH, and viscosity of the batch you intend to purchase, as these parameters directly impact performance in surface sizing applications. Request a certificate of analysis and, if applicable, a sample for lab testing to validate compatibility with your starch and paper grades.
Discuss packaging preferences, either 200 kg drums or 1000 kg IBC containers, and confirm the supplier’s lead time for bulk shipments from Weifang. Agree on Incoterms such as FOB Qingdao or CIF to your port, and clarify payment terms, as these are critical for international transactions. Ensure the port of discharge can handle the chosen packaging format.
For quality control, inspect the agent’s appearance, solid content, and pH upon receipt, and test its performance in a pilot run. Request documentation such as MSDS and compliance certificates for environmental or safety standards. Monitor the agent’s stability during storage and application, particularly in varying temperature conditions, to maintain consistent results.
