Preparation Information

• The surfaces to be bonded must be dry, clean, free of grease, free of dust and free of oil to ensure a reliable bonding.
• Prepare and pre-treat upper and sole materials carefully.

Processing Information

• Suitable Substrates - Various standard Upper/Sole footwear materials, Thermoplastic polyurethane, Polyurethane, Leather, Textile, PVC-soles, Halogenated TR- and rubber-soles
• Application Method - Brush and  Automatic application
• Coat both bonding surfaces of the pre-treated substrates with Ultraflex™ 4320 N using a suitable application method.
• Wait minimum the flash-off time for drying.
• Activate the substrate at the recommended activation temperature.
• Attach substrates and press.
• The pressure to be applied depends on the hardness of the substrates.
• Due to variation in working conditions and substrates we recommend to conduct preliminary tests for your intended application.
