Can You Request a Lower MOQ for Waterborne PU Crosslinker Hardener Samples?

GUANZHI's available commercial information lists 900 KG as the minimum order quantity for the relevant waterborne coating material. However, the product record refers to PA-3225, a water-based hydroxy acrylic dispersion used in two-component water-based coatings with hardener OS-9030, rather than a separately identified Waterborne PU Crosslinker hardener. A smaller evaluation quantity is not confirmed and must be discussed directly with the supplier.

MOQ Status and Product Identification

The published MOQ is 900 KG under GUANZHI's recorded research, manufacturing, and direct-sales model. This figure should be treated as the standard commercial requirement. Any request for a smaller sample quantity would require individual approval and a separate quotation.

Before requesting a sample, buyers should verify whether they need the PA-3225 binder, the OS-9030 hardener, or a complete two-component coating package. The supplied documentation identifies PA-3225 as a water-based hydroxy acrylic dispersion and does not classify it as a standalone Waterborne PU Crosslinker.

PA-3225 Performance and Formulation Role

PA-3225 is a hydroxy-functional polyacrylic secondary dispersion intended for water-based two-component coating systems. Its reported properties include strong water resistance, particularly during the initial curing stage, high gloss, good film fullness, compatibility with isocyanate curing agents, extended pot life, and rapid drying.

The dispersion is especially associated with hydrophobic HDI trimer and hardener OS-9030. These compatibility references may be useful when preparing a sample evaluation, but the final formulation should be confirmed with GUANZHI's technical team according to the intended substrate, application method, and performance targets.

Ordering, Quality, and Technical Support

Because no reduced MOQ is stated, the most practical approach is to submit a direct inquiry that specifies the desired quantity, application, target formulation, and whether a combined resin-and-hardener evaluation is required. GUANZHOU records factory quality control procedures covering solid content, pH, viscosity, and particle size distribution.

The product information also lists a 12-month shelf life, technical assistance, and free reference formulas after purchase. The stated lead time is 7-10 days. Depending on the order requirements, transportation can be arranged by sea, air, express courier, or rail. Payment terms are recorded as either 100% advance TT or 30% deposit with the remaining 70% payable before shipment.

Application Scope and Supplier Credentials

GUANZHOU's broader application coverage includes rail transit, engineering machinery, steel structures, hardware and appliances, automotive components, wood, plastics, construction materials, and flexible substrates. The supplied PA-3225 record does not assign the product to one specific application, so suitability should be confirmed during technical discussions.

The company reports a Quality Management System Certificate covering the research and production of environmentally friendly multipurpose water-based polyurethane coating materials and water-based coating additives. Its listed coating-sector cooperation cases include PPG and Nippon Paint.

Commercial and Technical Summary

Frequently Asked Questions

Can I negotiate a smaller MOQ for Waterborne PU Crosslinker hardener samples?

Yes, a lower quantity can be requested, but it is not confirmed as a standard option. The documented MOQ is 900 KG, so the supplier must approve any smaller sample order individually.

Does PA-3225 qualify as a Waterborne PU Crosslinker?

The available record does not make that classification. It describes PA-3225 as a water-based hydroxy acrylic dispersion and binder for two-component coatings, with particular compatibility with OS-9030 hardener.

What resources are available during product evaluation?

GUANZHOU lists technical support, formulation references, and free reference formulas after purchase. The stated shelf life for the product is 12 months.

Conclusion

The documented MOQ is 900 KG, and no standard lower MOQ has been established for Waterborne PU Crosslinker hardener samples. Buyers should first confirm the exact material required, distinguish PA-3225 from OS-9030, and request written approval for any smaller quantity. The supplier's direct-sales and manufacturing model allows technical discussions, while the listed delivery period is 7-10 days.
