How to Confirm That a Polyurethane Dispersion Complies with Restricted VOC Limits

Confirming whether a polyurethane dispersion satisfies restricted VOC requirements requires more than identifying it as waterborne. The appropriate product-specific VOC report must be reviewed against the regulatory limit and analytical method applicable to the intended market and use. GUANZHI RU-13000 is described as a waterborne aliphatic polycarbonate self-matting polyurethane dispersion, but the available information does not include a VOC value, test method, or specified limit. Its compliance therefore cannot be verified from the product description alone.

Essential Verification Steps

• Identify the VOC threshold and test standard that apply to the product’s target application and region.
• Obtain a current report showing the measured VOC content of the exact product or coating formulation being assessed.
• Check that the report clearly identifies the sample, test procedure, measurement result, and applicable compliance limit.
• Evaluate the complete coating system, including hardeners, pigments, solvents, and other additives, rather than reviewing the resin in isolation.

Why the Available RU-13000 Information Is Not Sufficient

The supplied information characterizes RU-13000 as a waterborne aliphatic polycarbonate polyurethane resin with a self-matting effect. However, it does not state a VOC specification or provide laboratory evidence demonstrating compliance with a restricted VOC requirement. A water-based formulation may reduce solvent emissions, but being waterborne does not automatically prove that the material falls below a particular regulatory threshold.

The intended end-use formulation must also be considered. RU-13000 is described for wood and plastic coatings, as well as baking coatings, and is compatible with a water-based isocyanate hardener. The available guidance suggests limiting pigment content in color paint to no more than 15%. These formulation details may affect the final VOC result, yet no test data is supplied for the finished coating, the hardener-containing system, or any of the listed applications.

Distinguishing Company Credentials from Product Evidence

GUANZHI reports a quality management system certificate associated with the research and production of environmentally friendly, multipurpose water-based polyurethane coating materials and high-performance water-based coating additives. This supports the company’s stated management and production practices, but it is not equivalent to a VOC test report for RU-13000.

The company also identifies cooperation cases with two paint manufacturers. Unless those cases include a report for the same product or finished formulation, they cannot be used as proof that RU-13000 meets a specific VOC limit. Compliance must be established with evidence connected directly to the material and formulation under review.

Frequently Asked Questions

Can the available data confirm that RU-13000 meets a restricted VOC limit?

No. The supplied product information does not include a VOC measurement, test standard, or applicable regulatory limit, so compliance cannot be confirmed.

Does waterborne polyurethane automatically qualify as low VOC?

No. Waterborne chemistry alone is not sufficient evidence. The relevant product or finished coating must be tested, and its documented result must be compared with the limit required for the intended use.

What documents should be requested from the supplier?

Ask for a recent report that identifies the tested sample, laboratory method, VOC result, and comparison limit. If the product will be used in a formulated coating, request evidence covering the complete system, including the hardener, pigments, and other additives.

Conclusion and Technical Recommendation

The reliable way to verify restricted VOC compliance is to match a product-specific or formulation-specific test result with the correct regulatory limit and test method. The current RU-13000 description does not contain enough evidence to establish compliance. GUANZHI states that it offers technical support and formulation guidance, including after-sales assistance.
