Can a Waterborne Isocyanate Crosslinker Match Your Curing Schedule?

A waterborne isocyanate crosslinker may be selected for a particular production schedule, but the available product information does not specify cure times, temperatures, or schedule-specific formulation changes. HPU-7790 is a polyol dispersion intended for waterborne two-component polyurethane coatings. Confirm the crosslinker pairing and curing conditions with the supplier before establishing production parameters.

Product Fit and Key Points

• HPU-7790 is a polycarbonate-structure polyol dispersion developed for soft-touch waterborne two-component polyurethane coatings.
• Its stated 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 publish cure schedules or adjustment guidance for these combinations.
• The product is described as solvent-free and organic-tin-free, with applications including automotive interiors and plastic products.

How to Assess Schedule Compatibility

Identify the components correctly

HPU-7790 is the polyol component, rather than an isocyanate crosslinker. It is designed to be combined with a poly-isocyanate to produce a waterborne two-component polyurethane coating. The product information highlights weather resistance, flexible film properties, soft touch, and scratch resistance, with a particular focus on waterborne plastic paints.

Confirm the formulation and process

OS-9016 and OS-9030 are named as suitable poly-isocyanates. However, the published information does not provide a mixing ratio, cure temperature, cure time, or formulation recommendations for different manufacturing schedules. These values should not be assumed from the product description; request confirmation for the intended coating system and production conditions.

When consulting the supplier, specify the substrate, end use, and required curing conditions. Guanzhi says technical support and free reference formulations are available. Its listed application areas include automotive interiors, household appliances, and plastic toys.

Information Available and Details to Verify

Frequently Asked Questions

Can HPU-7790 be paired with a waterborne isocyanate crosslinker?
