How to Evaluate Water-Based PU in a Production Trial

A production trial for water-based polyurethane (PU) can be planned around the stated 7–10 day delivery period for Polyisocyanate OS-9030. The minimum order is 900 KG. Once the material arrives, evaluate it in the intended two-component polyurethane formulation and on the substrates relevant to your application.

Plan the Trial Around Key Performance Checks

OS-9030 is a silicone-modified, HDI-based aliphatic polyisocyanate used as a curing agent in waterborne two-component polyurethane systems. Its stated formulation characteristics include solvent-free composition, low viscosity, easy dispersion, long pot life, and good weather resistance. These features make dispersion and handling useful starting points for a production-scale assessment.

During the trial, check dispersion behavior and mixed-system viscosity, then monitor pot life and storage stability. After application, assess water resistance, weather resistance, and the maximum film thickness achievable without blistering. Compare results with the requirements of the coating and the selected substrate.

Substrates and Application Areas

Potential metal applications include rail transit, engineering machinery, steel structures, hardware, household appliances, and automotive parts. Wood coatings for indoor or outdoor furniture are also among the suggested uses. The company additionally lists construction flooring, plastics, textiles, printing leather, inks, and adhesives as relevant substrate or application groups.

Formulation and Handling Considerations

OS-9030 is described as compatible with esters, ether esters, xylene, naphtha, and other listed solvents. When dilution is needed, use a urethane-grade solvent with water content below 0.05%. According to the product information, excess water may affect storage stability, so solvent quality should be checked as part of trial preparation.

The product has a stated shelf life of 12 months. Factory quality control, technical support, and free reference formulas are available to support evaluation. Guangzhou Guanzhi New Material Technology Co., Ltd. also records cooperation cases with PPG and Nippon Paint in China for coating applications.

Frequently Asked Questions

How soon can a production trial start?

The stated delivery cycle for OS-9030 is 7–10 days, subject to the 900 KG minimum order quantity.

What should be measured during evaluation?

Review dispersion, viscosity, pot life, water resistance, weather resistance, blister-free film thickness, and the stability of diluted material. Use the formulation and substrate intended for production wherever possible.

What solvent is recommended for dilution?

Choose a urethane-grade solvent with less than 0.05% water content. The product information cautions that higher water content may compromise storage stability.

Recommended Evaluation Approach

Allow for the delivery period, prepare the intended waterborne two-component PU formulation, and assess application and film performance against your production requirements. OS-9030 is supplied with factory quality control and technical support, and its listed shelf life is 12 months. For technical guidance or formulation support, contact sophia@guanzhihg.com.
