How to Screen HPU-7790 Against an Existing Waterborne Coating Formulation

Industrial coating resin samples can often be screened against an established formulation without starting with an extended trial program, provided that the coating chemistry, substrate, and required performance are clearly defined. GUANZHI Water-based Flexible Polyol Dispersion HPU-7790 offers a practical starting point for evaluating waterborne two-component polyurethane coatings, supported by technical guidance and free reference formulations.

Why HPU-7790 Is Suitable for Formulation Screening

HPU-7790 is a polyol dispersion incorporating a polycarbonate structure. It is formulated for use with poly-isocyanates in waterborne two-component polyurethane soft-touch coatings, making it relevant when an existing resin needs to be compared or replaced in a plastic coating system.

• High-elasticity film formation with a flexible, comfortable touch
• Scratch resistance and weathering performance
• Adhesion to plastic substrates
• Compatibility with waterborne plastic paint applications
• Potential use with GUANZHI poly-isocyanates, including OS-9016 and OS-9030

These properties make the material relevant to automotive components, vehicle interiors, household appliances, 3C electronic products, and plastic toys.

Recommended Evaluation Approach

1. Define the existing coating system

Before testing a new resin sample, identify whether the current formulation is a waterborne two-component polyurethane system and record the existing polyol, crosslinker, additives, pigment package, curing conditions, and application method.

2. Confirm the substrate and target properties

HPU-7790 is particularly relevant to plastic substrates. The comparison should focus on adhesion, elastic recovery, soft-touch feel, scratch resistance, weather resistance, appearance, and chemical or mechanical durability required by the final product.

3. Select a suitable co-reactant

As a polyol dispersion, HPU-7790 is intended to react with poly-isocyanates. GUANZHI lists OS-9016 and OS-9030 as suitable examples, providing a defined starting point for two-component system screening. Final compatibility still depends on the full formulation and application conditions.
