Can a Waterborne Isocyanate Crosslinker Match Your Curing Schedule?

Choosing a Crosslinker for Your Production Process

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

What the Product Information Confirms

• HPU-7790 is a polycarbonate-structure polyol dispersion developed for waterborne two-component polyurethane soft-touch coatings.
• Listed properties include weather resistance, adhesion to plastics, an elastic film, a soft-touch feel, and scratch resistance.
• OS-9016 and OS-9030 are identified by Guanzhi as suitable poly-isocyanates for consideration.
• The product is described as solvent-free and organic-tin-free, with applications including automotive interiors and plastic products.
• No curing schedule or parameters for adjusting the formulation to a specific schedule are provided.

Understanding the Components and Curing Requirements

HPU-7790 is the polyol component rather than an isocyanate crosslinker. It is designed to be combined with poly-isocyanates to make waterborne two-component polyurethane coatings. The stated performance profile includes weather resistance, touch elasticity, and scratch resistance, with a particular focus on waterborne plastic paints.

Although the product information names OS-9016 and OS-9030 as suitable poly-isocyanates, it does not specify a mixing ratio, curing time, curing temperature, or formulation guidance for different manufacturing schedules. These details should not be assumed from the product description. Confirm that the selected crosslinker and coating formulation can meet the conditions required for your application.

Information to Provide When Requesting Technical Advice

For a schedule-specific assessment, share the intended substrate, end use, and required curing conditions with the supplier. Ask for technical confirmation and a reference formulation suited to the process. Guanzhi states that technical support and free reference formulas are available. Its 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 research and production of environmentally friendly water-based polyurethane coating materials and water-based coating additives. The company also reports coating-related cooperation cases with two global paint and coatings companies; the available case information does not identify specific formulations or curing schedules.

Product Data and Items to Verify

Frequently Asked Questions
