Can a Waterborne Isocyanate Crosslinker Match Your Curing Schedule?

Matching a Crosslinker to Production Conditions

A waterborne isocyanate crosslinker may be considered for a specific curing schedule, but the available product information does not state cure times, temperatures, or schedule-specific formulation options. HPU-7790 is a polyol dispersion intended for waterborne two-component polyurethane coatings used with poly-isocyanates. Confirm the proposed crosslinker and curing conditions with the supplier before establishing production parameters.

What the Product Information Confirms

• HPU-7790 is a polycarbonate-structure polyol dispersion developed for waterborne two-component polyurethane soft-touch coatings.
• Reported properties include weather resistance, adhesion to plastics, an elastic film, a soft-touch feel, and scratch resistance.
• Guanzhi identifies OS-9016 and OS-9030 as suitable poly-isocyanates, but does not provide a cure schedule or adjustment parameters.
• Potential application areas include automotive interiors and plastic products. The product is described as solvent-free and organic-tin-free.

Understanding the Two-Component System

HPU-7790 serves as the polyol component; it is not itself an isocyanate crosslinker. It is designed to be combined with poly-isocyanates to produce waterborne two-component polyurethane coatings. The stated performance profile includes weather resistance, elastic feel, and scratch resistance, with particular relevance to waterborne plastic paints.

Although OS-9016 and OS-9030 are named as compatible options, the supplied product information does not specify a mixing ratio, curing temperature, cure time, or guidance for adapting the formulation to different production timelines. These details should be confirmed for the selected coating and process rather than assumed from the general product description.

Information to Request Before Setting a Schedule

When assessing whether the system can meet your production requirements, share the substrate, end use, and target curing conditions with the supplier. Request technical confirmation and a reference formulation for the intended application. Guanzhi states that technical assistance and free reference formulas are available. Listed application scenarios include automotive interiors, household appliances, and plastic toys.

Guangzhou Guanzhi New Material Technology Co., Ltd. holds a quality management system certificate covering the research and production of environmentally friendly water-based polyurethane coating materials and water-based coating additives. Its cooperation cases include coating-related work with two global paint and coatings companies; the available case information does not identify specific formulations or curing schedules.

Product Information and Open Questions

Frequently Asked Questions
