How to Trace Laboratory Samples to Production Records

To establish whether a laboratory sample corresponds to a production sample, compare the product reference, sample or batch number, production stage, and test results in the R&D and manufacturing documents. For PA-4823, look for records identifying the water-based hydroxyl acrylic emulsion and compare the factory inspection results for solid content, pH value, viscosity, and particle size distribution.

What to Check

• Use the same product reference, such as “Water Based Hydroxyl Acrylic Resin PA-4823,” in both laboratory and production records.
• Verify that the R&D sample and factory sample share a matching sample or batch identifier.
• Compare the documented solid content, pH value, viscosity, and particle size distribution results.
• Confirm that the recorded use is consistent with the product’s stated applications: wooden furniture, flooring, or kitchen painting.

Building a Traceable Record Link

A dependable link between a laboratory sample and a production sample should be supported by records that identify the product, sample or batch, processing stage, test data, and inspection or release status. When the product reference and identifier can be followed across R&D documentation and factory quality-control records, the connection is easier to substantiate.

PA-4823 is described as a water-based hydroxyl acrylic emulsion primarily intended for wooden furniture, flooring, and kitchen painting. Its product information lists factory quality control and names solid content, pH value, viscosity, and particle size distribution as inspection items. These parameters can be used to compare development findings with production testing, provided the corresponding records are available.

Guangzhou Guanzhi New Material Technology Co., Ltd. describes its operations as an R&D, manufacturing, and direct-sales model, with R&D and application centers in Guangzhou and Shanghai. Its production activities include water-based resins, water-based crosslinkers, water-based additives, and bio-based special polyols. This information indicates that development and production documentation may be reviewed, but it does not confirm that the company uses a particular electronic sample-tracking system.

The company also lists two certifications relevant to a documentation review. The QUALITY MANAGEMENTSYSTEMCERTIFICATE covers research and production of environmentally friendly multipurpose water-based polyurethane coating materials and high-performance environmentally friendly water-based coating additives. The Certificate of Intellectual Property ComplianceManagement System Certification covers intellectual property management for related research, development, and sales. Listed coating cooperation cases include PPG and Nippon Paint in China.

Record Comparison Guide

Frequently Asked Questions

Which product reference should I search for?

Look for “Water Based Hydroxyl Acrylic Resin PA-4823” and any associated product reference shown in the laboratory and production documentation.

Which quality measurements should be checked?

Compare solid content, pH value, viscosity, and particle size distribution. These are the inspection fields specified for the product.

Does the available information demonstrate that the records are linked?

No. The information describes R&D capabilities, production activities, and quality-inspection fields, but does not include actual records connecting a laboratory sample to a production batch. That connection must be verified from the underlying documents.

Conclusion and Next Steps

Start with the PA-4823 laboratory reference, locate the corresponding production sample or batch record, and check that the identifiers, quality results, and intended application agree.
