When polyurethane resin does not perform as expected, a successful compensation discussion depends on clear evidence rather than assumptions. Begin by preserving the container, product label, batch details, invoice, delivery documents, unused material, and storage records. Then compare the resin's measured properties with the specifications and test methods agreed with the supplier.
For Water Based Self-matting Polyurethane Resin RU-13000, the relevant quality-control indicators include solid content, pH value, viscosity, and particle size distribution. A written claim should explain the measured deviation, the application affected, and the documented commercial consequences.
Record the product name, batch number, quantity received, delivery date, transport condition, storage temperature, storage duration, and date of opening. Retain representative samples and production records so that both parties can review the same material and operating history.
Use the agreed specification and laboratory method when assessing solid content, pH value, viscosity, and particle size distribution. The issue may result from the resin, formulation conditions, storage, equipment, or application parameters, so the investigation should distinguish among these possibilities before a compensation amount is proposed.
Explain how the resin affected the intended coating process, including wood coatings, plastic coatings, or baking coatings. Relevant records may include rejected batches, rework, disposal, additional labor, production delays, or customer complaints. Claims should be limited to costs supported by purchase documents, manufacturing reports, waste records, or other traceable evidence.
RU-13000 is described as a waterborne aliphatic polycarbonate self-matting polyurethane dispersion. It is intended for wood, plastic, and baking coating applications, with a suggested pigment content of no more than 15% in the formulation.

Before negotiating a remedy, ask the supplier to conduct a technical review and provide its assessment in writing. The product information states that factory quality control, technical support, free reference formulas, and a 12-month shelf life are available. These resources can help determine whether the resin meets its specification under the actual formulation and processing conditions.
The requested remedy should correspond to the verified problem and the documented impact. Possible outcomes include replacement of the affected resin, a credit against a future order, reimbursement for directly supported costs, technical assistance, or another commercial adjustment accepted by both parties. Put the final agreement in writing, including the affected batch, corrective action, responsibility for transport or disposal, and the completion date.
Application records may cover indoor and outdoor wooden furniture, 3C digital products, automotive interiors, household appliances, rail transit, engineering machinery, and other coated materials. These examples should be used to explain the actual production impact, not to claim losses that cannot be demonstrated.

Its cooperation cases include a leading global paints and coatings manufacturer and a leading global provider of paints and coating services. The company also lists a Quality Management System Certificate and an Intellectual Property Compliance Management System Certification.
Prepare the product and batch information, invoice, delivery records, storage history, retained samples, laboratory results, production records, and evidence of rework, rejection, disposal, or interruption.
For RU-13000, the available quality inspection categories are solid content, pH value, viscosity, and particle size distribution. Results should be interpreted using the agreed specification and test procedure.
It is generally more effective to establish the defect, cause, and measurable impact first. After the evidence is reviewed, propose a remedy that matches the verified loss, such as replacement, credit, or another mutually agreed adjustment.
A defensible compensation request for defective polyurethane resin should combine batch traceability, controlled testing, application records, and a precise calculation of the business impact. For RU-13000, use solid content, pH value, viscosity, and particle size distribution as the main quality reference points, request a technical assessment, and document the agreed corrective action. Guangzhou Guanzhi lists a 900 KG minimum order and 7-10 day delivery time. For technical solutions or support, please contact sophia@guanzhihg.com.
