Importing Waterborne Isocyanate Crosslinker: Key Checks for OS-9013

Before importing a waterborne isocyanate crosslinker, review the product specifications alongside the commercial and shipping terms. For Water-reducible polyisocyanate OS-9013, this means confirming its identity, suitability for the intended waterborne resin, inspection details, shelf life, minimum order, lead time, payment arrangement, and freight option.

Start with Product Fit and Documentation

OS-9013 is a water-reducible aliphatic polyisocyanate intended for waterborne two-component polyurethane coatings. Its stated features include low yellowing, chemical resistance, flexibility, near-zero VOC description, and even dispersibility in waterborne resins. Compare these specifications with your coating requirements, and make sure the product name and characteristics on the order documents match the material being supplied.

Compatibility should be confirmed for the specific resin and formulation you plan to use. The product information describes even dispersion in waterborne resins, but importers should verify that this profile suits their own system and application. Listed application areas include rail transit, engineering machinery, steel structures, hardware and appliances, and automotive parts.

Quality Checks and Shelf Life

Ask what factory quality-control information is available for the shipment. The supplier lists solid content, pH, viscosity, and particle size distribution among its inspection items. Review the relevant quality documentation against the ordered product and delivered batch before accepting the material.

The stated shelf life is 12 months. Confirm the batch date and applicable shelf-life terms so the product will remain within that period upon receipt and when stored according to the agreed documentation. Formulation references and technical support are also listed as available for follow-up.

Confirm Commercial and Freight Terms

The supplier describes its operating model as research and development, manufacturing, and direct sales. The minimum order quantity is 900 KG, and the indicated delivery time is 7-10 days. Confirm that the quantity and schedule meet your requirements before arranging payment.

Listed payment terms are 100% advance TT or a 30% deposit with the remaining 70% due before shipment. Freight can be arranged by sea, air, express courier, or rail, depending on customer requirements. Agree on the payment and transport method before dispatch.
