How to Verify Acrylic Resin Documents Against the Shipped Batch

When the paperwork for an acrylic resin does not match the batch received, the material should not be technically accepted until its identity and quality records have been confirmed. For PA-4000, the verification process should connect the shipped product with the factory's quality-control data, stated application, and shipment information. The main quality references include solid content, pH value, viscosity, and particle size distribution.

Verification Priorities and Main Takeaways

• Check whether the documents identify the shipped material as Water Based Hydroxyl Acrylic Emulsion PA-4000.
• Compare the batch information with factory inspection data for solid content, pH value, viscosity, and particle size distribution.
• Confirm that the material remains suitable for waterborne two-component polyurethane wood coatings.
• Request technical assistance and formulation references if the documents cannot be clearly linked to the delivered batch.

How the Product Identity Should Be Confirmed

PA-4000 is a water-based hydroxyl acrylic emulsion intended to work with a water-dispersible isocyanate hardener in two-component polyurethane coatings. Because it serves as a defined component within a coating system, inconsistent paperwork can make it difficult to verify whether the supplied product corresponds to the expected formulation role.

The stated performance profile includes a clear, transparent matte film, rapid drying, high film hardness, good resistance to water and chemicals, and a long pot life. These properties should be assessed together with the product documentation and the factory's quality-control information rather than treated as separate claims.

Quality-Control Records to Request

Guangzhou Guanzhi New Material Technology Co., Ltd. identifies solid content, pH value, viscosity, and particle size distribution as quality inspection items. If the paperwork differs from the shipment, these measurements can serve as technical reference points for checking the material and resolving the documentation issue. The supplier also provides technical consultation and free reference formulas to assist with product confirmation and formulation work.

The company reports a Quality Management System Certificate for the research and production 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 for the intellectual property management of related research, development, and sales activities.

Business information supplied by the company lists cooperation cases with PPG and Nippon Paint in China, with coating identified as the application area. These examples demonstrate experience with coating customers, but they do not by themselves determine how a particular paperwork discrepancy should be resolved.

Frequently Asked Questions

Which details should be checked first when the paperwork and shipment differ?

Start with the product name, PA-4000 designation, intended application, batch information, and the available inspection data for solid content, pH value, viscosity, and particle size distribution.

Is PA-4000 suitable for wood coating applications?

PA-4000 is described for waterborne two-component polyurethane wood coatings, including systems that require clear transparency and strong chemical resistance. A technical review is recommended if the accompanying documents do not correspond with the received material.

What can the supplier provide during a documentation review?

The supplier lists technical support and free reference formulas for product and formulation clarification. The stated shelf life is 12 months.

Conclusion and Recommended Action

A discrepancy between acrylic resin paperwork and the delivered batch should be treated as an open verification matter until the product identity and quality information have been reconciled. For PA-4000, the key checks are its water-based hydroxyl acrylic emulsion designation, its role in waterborne two-component polyurethane wood coatings, and the factory data covering solid content, pH value, viscosity, and particle size distribution. Guangzhou Guanzhi combines research and development, manufacturing, direct sales, and technical support, making it appropriate to request formulation references or additional clarification when records do not align.
