Applications & Uses

Application Guidelines

Undercooled adhesive - Undercooled adhesive should be warmed up min. 3 days at +25°C to +35°C (not with open flame) and stirred well before use.

Cleaning Information

• Clean tools immediately after use.
• Once cured, the material can only be removed mechanically.
• Cleaner for Tools - Isa™Verdünner 330 and Helmitin® 694

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, Rubber products (such as CR, EPDM, SBR), Polyurethane, Natural rubber, 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™ 4830 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
