PUR Reactive Polyurethane Hot Melt Adhesive For Laminating Fabrics Of Outdoor Clothes
Introduction
PUR Reactive Polyurethane Hot Melt Adhesive For Laminating Fabrics To Film Membranes
PUR reactive polyurethane hot melt adhesive is widely used in the lamination of fabrics for outdoor clothing, where high performance, durability, and comfort are essential. This adhesive technology plays a critical role in bonding different functional layers—such as outer fabrics, waterproof membranes, and inner linings—into a single composite structure without compromising flexibility or breathability.
Advantages
- Maintains fabric softness and flexibility
- Provides strong bonding to membranes such as TPU, PU, and PTFE
- Excellent resistance to washing and weathering
- Suitable for waterproof and breathable fabric systems
Recommended processing conditions
- Application temperature: 120–140°C
- Melt viscosity: ~3,000 mPa·s at 120°C
- Application methods: Slot coating, spray, or roller coating
- Lamination pressure: Typically 0.2–0.6 MPa
Application
-
Functional fabric laminates (outdoor jackets, waterproof-breathable materials).
-
Footwear material and membrane bonding.
-
Automotive interior fabric bonding.
-
Medical and protective material composites.
Packing and Storage
- Unopened, it can typically be stored in a cool, dry place at 15–30°C for 6–12 months.
- Once opened, use promptly and keep sealed or under nitrogen protection.
- Packaging: 20kg or 200kg for one barrel.
