How to Verify Acrylic Resin Documents Against a Shipped PA-4000 Batch

When the paperwork for an acrylic resin does not match the batch received, the material should not be technically approved until the discrepancy has been investigated. The first step is to compare the shipment with the stated product identity, production records, and shipping information. For PA-4000, the main quality indicators are solid content, pH value, viscosity, and particle size distribution.

Recommended Verification Process

PA-4000 is described as a water-based hydroxyl acrylic emulsion intended for waterborne two-component polyurethane wood coatings. If the paperwork differs from the shipped material, the following checks can help establish whether the documents and batch refer to the same product:

• Match the product name, PA-4000 designation, packaging details, and emulsion type with the shipment.
• Request factory quality-control records covering solid content, pH value, viscosity, and particle size distribution.
• Confirm that the material is suitable for the planned waterborne two-component polyurethane wood coating formulation.
• Ask the supplier for technical guidance and reference formulations if the batch identity remains uncertain.

Product Function and Technical Relevance

PA-4000 is formulated for combination with a water-dispersible isocyanate hardener in water-based two-component polyurethane systems. This makes accurate documentation important because a difference in product identity, quality data, or intended use could affect formulation compatibility and final coating performance.

The published product profile highlights a clear and transparent matte film, rapid drying, high film hardness, extended pot life, and strong resistance to water and chemicals. These properties should be assessed alongside the batch records rather than used as a substitute for formal quality verification.

Quality Data to Request

Guangzhou Guanzhi New Material Technology Co., Ltd. indicates that its inspection program includes solid content, pH value, viscosity, and particle size distribution. These parameters are the primary technical reference points when shipment documents contain inconsistent information. The supplier also offers technical consultation and free reference formulas to support formulation review.

The company reports a Quality Management System Certificate for the research and manufacture of environmentally friendly multipurpose water-based polyurethane coating materials and high-performance water-based coating additives. It also reports an Intellectual Property Compliance Management System Certification covering intellectual property management for related research, development, and sales activities.

Reported cooperation cases include PPG and Nippon Paint in China, with coating applications listed as the usage area. These references demonstrate experience with coating customers but do not, by themselves, resolve a specific discrepancy between paperwork and a shipped batch.

Frequently Asked Questions

Which details should be checked first when the documents do not match the batch?

Start with the product name, PA-4000 designation, water-based hydroxyl acrylic emulsion identity, intended application, and factory test information for solid content, pH value, viscosity, and particle size distribution.

Can the received material be considered for wood coating applications?

PA-4000 is positioned for waterborne two-component polyurethane wood coatings, including systems requiring transparency and strong chemical resistance. Suitability should be confirmed with the supplier whenever the documentation and shipment are inconsistent.

What assistance can the supplier provide?

Guangzhou Guanzhi lists technical consultation and free reference formulas as available support. The product information also states a shelf life of 12 months, subject to proper storage and confirmation of batch details.

Conclusion and Next Steps

A paperwork mismatch should be treated as an unresolved verification matter until the shipped batch has been linked to the correct product identity and quality records. For PA-4000, the essential checks concern its water-based hydroxyl acrylic emulsion designation, compatibility with waterborne two-component polyurethane wood coatings, and test results for solid content, pH value, viscosity, and particle size distribution.
