How to Document an Underperforming Water-Based Resin Sample

When a water-based resin sample does not meet expectations, a well-organized test record helps technical support evaluate what happened. Link the product and batch to the substrate, application, preparation, curing conditions, and specific results. For UV-5274, include observations about coating appearance, adhesion, wear, and chemical resistance, along with the actual curing parameters.

Start with the Sample and Test Context

Record the product name, batch number if available, sample date, and sample condition. Note the intended application, the substrate used, and how the coating was prepared and applied. Describe the defect in observable terms—for example, poor adhesion or low gloss—rather than recording an assumed cause.

UV-5274 is identified for plastic substrates such as ABS, PC, and ABS/PC, with automotive interiors and household appliances among its listed application areas. State the exact substrate and end use in your report so the result can be considered in context.

Capture the Process and Results

Write down the complete preparation and curing sequence, including any difference from the reference conditions. For UV-5274, the stated process is a 5-minute hold at room temperature followed by 10 minutes at 60 C. The listed lighting energy is 800 + 100 mJ/cm2, and the intensity is 100 + 20 mW/cm2. Record the measured or set values actually used, not just the target settings.

Describe the coating's appearance and report relevant performance observations, such as adhesion, hardness, wear resistance, and chemical resistance. The product information presents these as performance features but does not provide pass/fail thresholds or a troubleshooting test sequence. Keep observations separate from conclusions and share the record with technical support when the cause is unclear.

Product Details to Include

UV-5274 is described as a solvent-free, UV-curing polyurethane acrylate dispersion with high crosslinking density. Its stated characteristics include high gloss and fullness, as well as wear and chemical resistance and adhesion to ABS, PC, and ABS/PC.

The product is often used alongside the high-flexibility resin UV-5270, but no mixing ratio is specified in the supplied product information. If UV-5270 or another resin, additive, or material was included, document its identity and quantity rather than relying on an assumed formulation.

Frequently Asked Questions

What curing information belongs in the report?

Include the actual room-temperature hold, heating duration and temperature, lighting energy, and light intensity. Compare those values with the listed UV-5274 reference process and note any differences.

Which substrates are specified for UV-5274?

The product information names ABS, PC, and ABS/PC. Identify the specific material tested, since performance observations should be tied to the substrate and application.

Are there published acceptance criteria or troubleshooting steps?

The supplied information does not define acceptance limits or a diagnostic protocol. Report what you observed and the conditions used, then ask technical support for guidance instead of treating an unstated threshold as a specification.

Next Steps

A useful evaluation record connects the UV-5274 product and substrate with the preparation, curing process, and measured or observed performance.
