Working Principle
PUR hot melt adhesive features a dual-curing mechanism:
- Stage 1: Heated to 100-140°C, it melts and bonds substrates. Cooling provides initial mechanical strength (thermoplastic phase)
- Stage 2: Reacts with ambient moisture to form crosslinked polyurethane network, achieving final high strength and chemical resistance (reactive curing phase)
Key Features & Advantages
Environmental Safety
- Low VOC/Odor: Meets stringent automotive cabin air quality standards
- Solvent-Free: 100% solids content with no harmful emissions during curing
Performance Excellence
- Weather Resistance: No cracking at -40°C, no debonding at 150°C
- Bond Strength: Excellent adhesion to metal, plastic (PP/ABS/nylon), and fabric substrates
Production Efficiency
- Fast Curing: Fully cures within 8 hours, shortening production cycles
- Energy Efficient: No deodorization or complex post-processing required, reducing energy consumption by 30%

Frequently Asked Questions
What is PUR hot melt adhesive?
PUR (Polyurethane Reactive) hot melt adhesive is a reactive curing adhesive. It first bonds like a thermoplastic hot melt when cooled, then chemically reacts with ambient moisture to form a crosslinked polyurethane network.
How does PUR hot melt adhesive differ from traditional hot melts?
It provides higher heat resistance, durability, and chemical resistance compared to traditional hot melts.
What interior parts commonly use PUR hot melt adhesives?
Typical applications include dashboard skins, door panels, headliners, pillar trims, trunk trims, seat decorative parts, and speaker covers.
