Product Overview
PUR hot melt adhesive (Polyurethane Reactive Hot Melt Adhesive) is specifically engineered for automotive interior applications, offering exceptional bonding performance across diverse materials and challenging operating conditions.
Working Principle
PUR hot melt adhesive features a dual-stage reactive curing mechanism:
- First Stage: Heated to 100-140°C, the adhesive melts and is applied to substrates. Upon cooling, it develops initial mechanical strength (thermoplastic phase)
- Second Stage: Reacts with ambient moisture to form crosslinked polyurethane networks, achieving final high strength and chemical resistance (reactive curing phase)
Key Features & Advantages
- Strong Initial Tack: Parts can be handled and formed immediately after cooling without displacement
- Wide Temperature Range: Performs reliably from -40°C to 120°C, withstanding interior thermal cycles
- Humidity & Chemical Resistance: Passes 85°C/85%RH tests; resistant to aging, alcohol, and cleaning agents
- Multi-Substrate Compatibility: Excellent adhesion to PP, ABS, PVC, PU, fabric, and leather materials
- Eco-Friendly Formula: Solvent-free composition compliant with vehicle interior VOC and odor regulations
- Flexible Performance: Maintains elasticity after curing to accommodate thermal expansion and vibration
Automotive Applications
- Dashboard skin lamination (PVC/TPO film + foam + substrate)
- Door panel lamination (PU/PVC leather + foam + PP base)
- Headliner bonding (fabric + foam)
- Pillar trims, trunk trims, seat decoration parts, and speaker covers
Packaging & Storage
Available in 20kg or 200kg sealed barrels. Store in clean, dry conditions with a 6-month shelf life.
Frequently Asked Questions
Q: What is PUR hot melt adhesive?
A: PUR (Polyurethane Reactive) hot melt adhesive is a reactive curing adhesive that first bonds like a thermoplastic hot melt when cooled, then chemically reacts with ambient moisture to form crosslinked polyurethane networks.
Q: How long is the open time for lamination?
A: Typically 30 seconds to several minutes, requiring precise process control and often automated application equipment.
Q: How long does it take to achieve full curing?
A: Initial handling strength is obtained after cooling, while final curing requires approximately 24 hours depending on humidity and temperature conditions.
