Reactive PUR Hot Melt Adhesive for Textile Lamination and Technical Fabric Bonding

Reactive PUR Hot Melt Adhesive for Textile Lamination and Technical Fabric Bonding

Reactive polyurethane (PUR) hot melt adhesives occupy a unique position in textile lamination. They are applied as a thermoplastic melt, like any hot melt, but then crosslink with ambient moisture to form a thermoset bond that will not re-melt. The result is a laminate that survives washing, dry cleaning, steaming and long-term flexing far better than conventional hot melt films, while the process remains completely solvent-free.

JCC manufactures a full range of moisture-curing PUR grades for cloth-to-film, cloth-to-cloth and film-to-film lamination. The adhesives are used in performance outerwear, medical and protective textiles, automotive trim, home textiles and technical composites where a durable, soft and breathable bond is essential.

The Advantage Over Conventional Lamination

• Thermoset bond strength: after curing the adhesive no longer melts, so laminates resist heat, steam and repeated industrial laundering.
• High green strength: immediate handling strength after nip rollers allows in-line cutting, folding and packing without a curing rack.
• Low application weight: 8-25 gsm is normally sufficient, keeping the laminate soft and breathable.
• Solvent-free and low VOC: no solvent recovery, no oven, no explosion-proof zone and significantly lower operating cost.
• Excellent hydrolysis and ageing resistance: suitable for outdoor, automotive and medical applications.
• Wide substrate compatibility: bonds textiles to TPU film, PU film, PVC, foam, non-woven and metal foil.

Grade Selection Guide

Processing Notes

• Application temperature is typically 120-140 degrees Celsius, adjusted to the viscosity profile of the grade.
• Moisture curing takes 24 to 72 hours depending on ambient humidity, film thickness and substrate permeability.
• Rolls must be stored sealed below 30 degrees Celsius to prevent premature curing in the package.
• Cleaning is carried out with standard PUR flushing agents, no chlorinated solvents required.

Applications

• Waterproof and breathable outerwear laminates
• Medical gowns, drapes and protective apparel
• Automotive interior trim and headliner film bonding
• Refrigerator covers and appliance panel lamination
• Furniture and woodworking edge bonding
