How to Document a Poor-Performing Water-Based Resin Sample

When a water-based resin sample does not meet expectations, a clear test record helps distinguish the observed issue from its possible causes. For UV-5274, connect the sample’s identity and substrate to the coating results, preparation steps, and actual curing conditions before requesting technical assistance.

Build a Complete Sample Record

Start with the product name, batch identifier if available, sample date, and the condition of the material. Record the substrate, intended application, preparation method, application details, and any other resins or additives used, including their amounts. The product information notes that UV-5274 is often used with the high-flexibility resin UV-5270, but it does not specify a blend ratio.

Describe results in measurable or directly observable terms. For example, note the coating’s appearance and gloss, or report observed adhesion, hardness, wear resistance, and chemical resistance. Keep observations separate from explanations: record that adhesion was poor rather than attributing the result to a particular cause without evidence.

Compare the Test Process with the Reference Conditions

For each test, document the actual room-temperature hold, heating time and temperature, lighting energy, and light intensity. The listed UV-5274 reference conditions are a 5-minute hold at room temperature followed by 10 minutes at 60 C, with lighting energy of 800 + 100 mJ/cm2 and intensity of 100 + 20 mW/cm2. Note every difference from these conditions alongside the test result.

These values are provided as reference process information, not as acceptance criteria. The available product data does not define pass/fail limits or a troubleshooting test sequence, so avoid treating an unstated threshold as a specification.

Product Context and Test Scope

UV-5274 is described as a solvent-free, UV-curing polyurethane acrylate dispersion with high crosslinking density. Its stated features include high gloss and fullness, wear and chemical resistance, and adhesion on ABS, PC, and ABS/PC. Record the exact substrate used, since the product information also identifies automotive interiors and household appliances as application scenarios.

Frequently Asked Questions

What curing information belongs in the report?

Record the actual hold duration and temperature, followed by the lighting energy and intensity. Compare those figures with the UV-5274 reference conditions and identify any deviations.

Which substrates are listed for UV-5274?

The product information names ABS, PC, and ABS/PC. Include the specific substrate in each test record so the results remain tied to the material and intended application.

Are pass/fail thresholds or diagnostic tests specified?

No. The supplied information does not provide acceptance limits or a troubleshooting protocol. Document the results and process conditions, then consult technical support for further assessment.

Next Steps

A useful report links the UV-5274 product and sample condition with the substrate, preparation, curing process, and observed performance. Guangzhou Guanzhi states that technical support and formulation references are available. For product-specific assistance, contact sophia@guanzhihg.com.
