How to Validate Hardener Ratios and Line Speed for PU-1036

What the Available Data Confirms

The current product information does not provide a custom hardener ratio or a validated production-line speed for PU-1036. As a result, a specific formulation ratio cannot be calculated from the supplied data. Before adjusting the recipe or increasing line speed, consult technical support to confirm compatibility, curing requirements, and processing conditions.

PU-1036 Product Profile

PU-1036 is described as a waterborne polyurethane dispersion designed for transparent coatings on leather, PVC, and other substrates. The listed performance characteristics include a high-gloss transparent appearance, a hard film, scratch resistance, and adhesion to leather and PVC.

These properties can help frame a formulation discussion, but they do not establish whether an additional hardener is required or define the appropriate component ratio. The product information also does not state drying, curing, coating-weight, or line-speed parameters.

Formulation and Production Considerations

A production line should be evaluated according to the substrate, coating method, drying equipment, film thickness, and required final performance. Since no hardener identity, mixing procedure, or operating window is listed for PU-1036, production settings should be confirmed through supplier guidance and application testing instead of being inferred from the product description.

Guangzhou Guanzhi New Material Technology Co., Ltd. lists technical support and free reference formulas for product users. These resources can help determine whether a crosslinker is needed, establish a suitable ratio, and validate line conditions for the intended flexible-material application. The product record states a 12-month shelf life.

Application Scope and Supplier Capabilities

The company identifies textile, printing leather, ink, and adhesive as flexible-material application areas. Its profile describes research and application centers in Guangzhou and Shanghai, along with more than 50 invention patents. The company also lists a quality management system certificate covering the research and production of environmentally friendly water-based polyurethane coating materials and water-based coating additives. Two customers in the coatings sector are named in the company profile, but no case-specific hardener ratio or production-speed data is supplied.

Information Required Before Scale-Up

Frequently Asked Questions

Is a custom hardener ratio available for PU-1036?

No. The supplied product data does not identify a hardener or specify a mixing ratio.

Can the product description determine the production-line speed?

No. No line-speed target or validated processing range is included. The appropriate settings should be established with technical support and application trials.

Which product features should be discussed with the supplier?

Relevant information includes the transparent high-gloss film, hardness, scratch resistance, adhesion to leather and PVC, and intended use on leather, PVC, and other substrates.

Conclusion and Next Steps

The available information is insufficient to recommend a numerical hardener ratio or production-line speed for PU-1036. Treat both values as application-specific variables that require supplier confirmation and validation testing. The product record lists a 900 kg minimum order quantity and a delivery period of 7–10 days. For technical solutions or formulation support, contact Sophia Chao at sophia@guanzhihg.com.
