Q1: What are the primary application areas for Tongde PUD6222?
A: Tongde PUD6222 is widely used in water-based leather finishing systems, textile coatings, and flexible packaging laminates where high film clarity, excellent abrasion resistance, and good low-temperature flexibility are required.
Q2: Can PUD6222 be blended with other waterborne resins or additives?
A: Yes, PUD6222 exhibits good compatibility with common waterborne acrylics, polyvinyl acetate (PVAc), and crosslinkers such as aziridine or carbodiimide types—though compatibility testing under actual formulation conditions is recommended prior to full-scale use.
Q3: How should PUD6222 be stored and handled to maintain stability?
A: Store in tightly sealed containers at temperatures between 5°C and 35°C, away from direct sunlight and freezing conditions. Avoid prolonged exposure to high pH environments or strong oxidizing agents, as these may affect colloidal stability.
Q4: Does PUD6222 require a coalescing agent or organic solvent for film formation?
A: No, PUD6222 is designed for true waterborne film formation and typically achieves satisfactory coalescence without added solvents or traditional coalescents under standard drying conditions.
