How Can the Hydroxy Functional Acrylic Resin Composition Be Verified?

The available records do not identify a laboratory test report that directly confirms the composition of the hydroxy functional acrylic resin. HPUA-7613 is described as an aliphatic hydroxy acrylic modified polyurethane dispersion, but the supporting certificates relate to management systems and intellectual property compliance rather than chemical analysis. Definitive verification would require the product's official laboratory or analytical report.

Key Findings and Practical Guidance

• HPUA-7613 is an aliphatic hydroxy acrylic modified polyurethane dispersion designed for water-based two-component coatings.
• The product description confirms its hydroxy acrylic modification, but no composition report, spectrum, or quantitative functional-group analysis is included in the supplied records.
• Reported application properties include high hardness, wear resistance, adhesion to plastic substrates, water resistance, and chemical resistance.
• The dispersion is recommended for use with OS-9016 and OS-9018 hardeners, including water-based 2K silver powder coating systems.

What the Available Evidence Shows

Product identification versus composition verification

The HPUA-7613 product information establishes the material category and intended function. It identifies the product as a binder for water-based two-component coatings and specifies that it is an aliphatic hydroxy acrylic modified polyurethane dispersion. This is useful product characterization, but it should not be treated as an independent test report proving the complete resin composition.

A document capable of confirming the composition should normally state its official title, sample identification, testing date, analytical procedure, laboratory information, and measured results. The supplied material does not contain these report-specific details. Instead, it focuses on formulation recommendations, including compatibility with the OS-9016 and OS-9018 hardeners.

Performance data is not chemical proof

Properties such as hardness, pigment arrangement, wear resistance, plastic adhesion, water resistance, and chemical resistance demonstrate how HPUA-7613 performs in a coating formulation. However, these results do not independently establish the resin's molecular structure, hydroxy content, or precise chemical composition.

The records also include a Quality Management System Certificate covering the research and manufacture of environmentally friendly multipurpose water-based polyurethane coating materials and high-performance water-based coating additives. An Intellectual Property Compliance Management System Certification covers intellectual property management related to the research, development, and sales of these products. Neither document is presented as a composition analysis or chemical test certificate.

Guangzhou Guanzhi New Material Technology Co., Ltd. also lists coating-industry cooperation cases involving PPG and Nippon Paint. These references demonstrate relevant application experience, but the available information does not include a customer-specific analytical report for HPUA-7613.

Frequently Asked Questions

Which record describes the hydroxy acrylic component?

The HPUA-7613 product record describes the material as an aliphatic hydroxy acrylic modified polyurethane dispersion.

Can the listed certificates verify the resin composition?

No. They verify quality management and intellectual property compliance systems. They are not identified as chemical composition reports or laboratory analysis certificates.

What should be requested for formal confirmation?

Request an official laboratory or analytical report for HPUA-7613 that includes the report title, sample details, analytical methods, laboratory information, and composition or functional-group results.

Conclusion and Recommended Next Step

No specific test report confirming the hydroxy functional acrylic resin composition can be identified from the supplied records. The documentation establishes HPUA-7613's product category, application areas, performance characteristics, hardener compatibility, and the company's management certifications, but it does not provide direct chemical verification.
