Q1: What are the primary application areas for Tongde PUD6228H?
A: Tongde PUD6228H is widely used in high-performance waterborne coatings for flexible substrates, including synthetic leather finishing, textile coatings, and soft-touch decorative films. Its excellent film-forming ability and low-temperature coalescence make it especially suitable for heat-sensitive materials.
Q2: How does PUD6228H perform in terms of chemical resistance and mechanical durability?
A: PUD6228H delivers balanced resistance to mild solvents, alcohols, and common cleaning agents, along with strong tensile strength and elongation—ideal for applications requiring repeated flexing or abrasion resistance. Performance may vary depending on film thickness and crosslinking conditions.
Q3: Can PUD6228H be blended with other waterborne resins or additives?
A: Yes, PUD6228H exhibits good compatibility with many acrylic emulsions, waterborne polyesters, and standard formulation additives such as defoamers, wetting agents, and rheology modifiers—provided pH and ionic stability are maintained within recommended ranges.
Q4: What is the typical solids content and viscosity range of PUD6228H?
A: As a ready-to-use dispersion, PUD6228H typically features a solids content in the range of 30–35% and a Brookfield viscosity (at 25°C, spindle #3, 20 rpm) generally between 500–2500 cP—subject to batch variation and measurement conditions.
