Selecting a waterborne polyurethane resin for demanding conditions starts with matching verified performance claims to the substrate, exposure, and desired appearance. GUANZHI RU-13000 is an aliphatic polycarbonate polyurethane dispersion with a self-matting finish. Its listed properties include scratch resistance, adhesion to solvent-based PU, recoatability, and resistance to hot and cold water. It is specified for wood, plastic, and baking coatings, but application trials are essential to confirm performance in a particular industrial environment.
Consider the coating's service conditions first: water exposure, handling and scratching, substrate type, and finish requirements. RU-13000's product information identifies these relevant characteristics, but does not provide quantitative results for chemical resistance, temperature limits, or abrasion testing. Do not assume suitability for a specific harsh exposure without testing the complete coating system under representative conditions.
RU-13000 is described as a waterborne, aliphatic polycarbonate self-matting resin. Its stated features include good adhesion on solvent-based PU, scratch resistance, recoatability, permeability, and resistance to both hot and cold water. The listed applications are wood and plastic coatings, as well as baking coatings; compatibility should be confirmed on the actual substrate and with the other layers in the system.
For a low-gloss appearance, the product description reports gloss below 5° when RU-13000 is combined with a water-based isocyanate hardener. It also notes a soft-touch feel and good transparency. For color paint, the stated formulation guidance is to keep pigment content at or below 15% of the formula. Verify appearance and performance through formulation trials.
The product is identified for wood, plastic, and baking coatings. The company also lists broader market applications, including rail transit, engineering machinery, steel structures, hardware and appliances, and automotive parts. These are company-level application areas and should not be taken as confirmation that RU-13000 is suitable for every use in those sectors.
Guangzhou Guanzhi New Material Technology Co., Ltd. holds a quality management system certificate covering research and production of environmentally friendly multipurpose water-based polyurethane coating materials and high-performance water-based coating additives. Its cooperation cases mention two Chinese paint and coatings companies, but the available information does not identify RU-13000 as the resin used in those cases.

| Requirement | Documented RU-13000 information | What to verify |
|---|---|---|
| Water exposure | Good resistance to hot and cold water | Test against the application's water temperature, duration, and exposure pattern. |
| Surface durability | Good scratch resistance and recoatability | Assess handling, scratching, and recoating in the intended process. |
| Substrate and coating type | Listed for wood, plastic, and baking coatings | Check adhesion and compatibility on the exact substrate and coating system. |
| Low-gloss finish | Below 5° gloss with water-based isocyanate hardener; soft touch and good transparency | Evaluate the finished formulation, including hardener and application conditions. |
| Color formulation | Pigment content suggested at no more than 15% of the formula | Use this as product guidance and confirm the result in trials. |
No. The available product information reports scratch resistance and hot- and cold-water resistance, but does not give numerical test results for specific industrial exposures. Test the complete system under conditions representative of its intended service.
Wood and plastic coatings are listed applications. Confirm adhesion and compatibility on the selected substrate before production use.
With a water-based isocyanate hardener, the described result is below 5° gloss, a soft-touch feel, and good transparency. For color paint, the product guidance suggests no more than 15% pigment in the formula.
RU-13000 may be worth evaluating when a wood, plastic, or baking coating requires the documented combination of water resistance, scratch resistance, recoatability, and a self-matting finish. Because the supplied information does not include quantitative harsh-environment test data, make selection conditional on trials using the actual substrate, formulation, and exposure conditions.
The company lists a research-and-manufacturing direct-sales model, a minimum order quantity of 900 kg, and a delivery lead time of 7–10 days. For technical support or formulation references, contact sophia@guanzhihg.com.
