HSR-6280 Water-Based Polyurethane Spray Adhesive
Model: HSR-6280
Fast-drying water-based polyurethane spray adhesive with high initial tack, water resistance and yellowing resistance.
- Fast drying and high initial tack
- Water resistance and yellowing resistance
- For foam, fabrics, leather and selected plastic/metal assemblies
Packaging: 20 kg / pail
Overview
Fast drying. High initial tack. HSR-6280 is an anionic water-based polyurethane dispersion spray adhesive for multi-material bonding. The supplied TDS describes high solids, strong cohesion, water resistance and yellowing resistance, supporting demanding furniture, loudspeaker, automotive interior and leather goods assemblies.
Recommended substrate families include foam, fabrics, PVC leather, XPE, PU foam and nonwoven materials. Verify adhesion on the actual substrate grade and surface treatment. Allow 10–30 minutes of flash-off before joining and pressing; the supplied TDS reports best tensile strength after approximately 24 hours.
Automotive & transport interior wrapping
Application areas include seat foam wrapping, door panel trim, dashboards, armrests, headliners and spare-wheel cover boards. The same application direction extends to high-speed rail and coach interiors, subject to the applicable material and assembly requirements.
Selection requirements: heat resistance, low odor and automotive-grade VOC control. Confirm the required temperature range, odor limits and VOC test methods with the customer, and validate the actual adhesive grade and completed assembly against those requirements.

Application & handling
Prepare clean, dry surfaces free of oil and contamination; use substrate-compatible cleaning and pretreatment.
Spray a thin, even fan-shaped film at approximately 15–20 cm from the surface. Avoid excessive or insufficient coverage.
Allow 10–30 minutes of flash-off before joining and applying suitable pressure. Adjust for temperature, humidity, coating thickness and substrate. Best tensile strength develops after approximately 24 hours, per the supplied TDS.
Apply at 5–45°C with RH below 80%. Store and transport at 5–45°C; protect from freezing and direct sunlight. Reseal the pail promptly after use to reduce skin formation.
If dilution is needed, use deionized water only and confirm the dilution level with the supplier; tap water may destabilize the emulsion.
Flush spray equipment thoroughly with clean water immediately after use. Use suitable ventilation and personal protection according to the current product-specific SDS.
Confirm current grade-specific technical and safety data, and validate performance on your actual parts before production.
