Q1: What are the primary application areas for YA-S 920?
A: YA-S 920 is widely used in high-performance waterborne coatings for flexible substrates—including synthetic leather, textiles, and automotive interior trims—where excellent film flexibility, abrasion resistance, and low-temperature performance are required.
Q2: Can YA-S 920 be blended with other waterborne resins or additives?
A: Yes, YA-S 920 demonstrates good compatibility with common waterborne acrylics, polyacrylates, and crosslinkers such as aziridine or carbodiimide types—though compatibility testing under specific formulation conditions is recommended prior to full-scale use.
Q3: How does YA-S 920 perform in terms of film formation and drying behavior?
A: YA-S 920 forms continuous, cohesive films at ambient temperatures with typical coalescence occurring between 15–25°C. Drying time is formulation-dependent but generally benefits from moderate air circulation and controlled humidity during the initial film-setting stage.
Q4: Is YA-S 920 suitable for low-VOC or regulatory-compliant formulations?
A: Yes—YA-S 920 is a true waterborne polyurethane dispersion with negligible organic solvent content, supporting formulators in meeting stringent global VOC reduction targets and sustainability-driven regulatory expectations.
