Q1: What is the primary application field for ALBERDINGK U 9380?
A: ALBERDINGK U 9380 is primarily designed as a high-performance waterborne polyurethane resin for use in premium industrial coatings, including protective topcoats for wood, metal, and plastic substrates where excellent flexibility, abrasion resistance, and low-VOC compliance are required.
Q2: Is ALBERDINGK U 9380 compatible with common waterborne acrylic or epoxy dispersions?
A: Yes, ALBERDINGK U 9380 exhibits good compatibility with many standard waterborne acrylic dispersions and modified epoxy emulsions, enabling hybrid formulations. Compatibility testing under actual processing conditions—especially regarding pH, ionic strength, and shear—is recommended before full-scale integration.
Q3: How should ALBERDINGK U 9380 be stored to maintain stability?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, away from freezing and direct sunlight. Prolonged exposure to temperatures below 5 °C may cause irreversible viscosity changes or phase separation; allow gradual equilibration to room temperature before use if chilled.
Q4: Does ALBERDINGK U 9380 require neutralization or pH adjustment prior to use?
A: ALBERDINGK U 9380 is supplied as a self-emulsified, anionically stabilized dispersion and typically does not require additional neutralization. However, formulation pH should be maintained within the range of 7.5–9.0 to ensure optimal colloidal stability and film formation performance.
