Service Life / Durability
Usage Guide
This polyurethane adhesive offers reliable bonding when applied under proper environmental and substrate conditions. Correct mixing (for 2K systems) and curing are essential for achieving optimal mechanical strength.
Surface Preparation
Ensure surfaces are clean, dry, and free of grease. For metals or composites, light abrasion or primer may enhance bonding performance.
Application Process
Apply adhesive evenly to one or both substrates. For 2-component systems, mix components at the recommended ratio and use within the pot life. Use manual, pneumatic, or automated dispensing depending on production needs.
Curing Conditions
Moisture-curing PU: reacts with atmospheric moisture
2K systems: cure according to mixing ratio and environmental temperature
UV-curing PU: requires specified wavelength exposure
Curing speed varies with temperature, humidity, and adhesive thickness.
Key precautions for this type of product
- Avoid applying in high-humidity environments for moisture-curing grades.
- Ensure accurate mixing ratio for 2K adhesives.
- Do not expose uncured PU to strong solvents.
- Recommended application temperature: 10°C – 35°C.
