Hot Melt Adhesive Swift Lock 4955 M on Polyurethane Base
Polyurethane-base hot melt adhesive Swift Lock 4955 M is used for the lamination of profile products made of aluminum, PVC, and wood, such as chipboard, MDF, plywood with decorative PVC films, veneer, CPL (Continuous Pressure Laminate – Melamine), and other materials.
Characteristics:
- Light-colored hot melt adhesive with excellent machining characteristics
- Very good heat stability and heat resistance
- Fast setting and high initial tack
- High viscosity and adhesion, allowing coverage of thick, rigid, problem films, and veneer
- Increased heat resistance and moisture resistance after curing

Applications:
- Can be applied using rollers, nozzles, or other applicator systems.
- During lamination, it is recommended that the temperature of metal surfaces be maintained at +40°C.
- In the case of PVC profiles, heating significantly improves the quality of adhesion and helps reduce glue consumption. The optimum profile temperature before gluing should be between +30°C and +35°C.
- For optimal results, bonded materials must be clean, dry, and free from dust and grease.
- Full hardening of the adhesive is achieved after 5-7 days at 20°C and 65% relative humidity.
- Immediately after mechanical bonding, the products are ready for further processing (cutting and formatting).
- Equipment for glue melting should be protected from atmospheric moisture.
Storage Conditions:
- Glue should be stored in a closed original package under cool and dry conditions at room temperature (+15°C to +30°C) with a minimum relative humidity of 30%.
- Protect from direct sunlight.
- Under these conditions, glue can be stored for at least 12 months without affecting its quality.
