Solvent-Based Polyurethane Adhesive for Sole Bonding

PU 689 is a polyurethane adhesive developed for shoe sole bonding processes. Designed for manual application, it can be used independently or in combination with heat activation (e.g., vulcanizing equipment) to improve performance in demanding joints.

Technical Features:

• High Initial and Final Strength: Provides immediate holding power and long-term bond resistance.
• Good Brushability: Ensures smooth and uniform application without buildup.
• High Performance: Delivers efficient coverage with reduced product consumption.
• Hot Tack: Suitable for processes involving preheating.
• Optical Indicator: Facilitates verification of adhesive application.

Recommended substrates:

• Textiles and leathers
• PVC and expanded PVC
• Polyurethane
• Croupon
• TR and expanded TR
• Neolite
• EVA
• Rubber
• Crepe
• PVC and polyurethane synthetics
• Fatty, semi-oily, dry and waxed leathers
