Solvent-Based Polyurethane Auxiliary for Surface Preparation

Primer PU 85 is an auxiliary developed for surface preparation in footwear and leather goods manufacturing. It enhances adhesion on substrates intended for bonding with polyurethane adhesives.

Technical Features:

• Optical Indicator: Facilitates visual control during application.
• High Penetration: Ensures uniform treatment across the substrate.
• High Performance: Provides greater coverage with reduced product consumption.
• Good Brushability: Enables smooth and uniform application.
• Vulcanizer compatibility: Can be used alone or in combination to improve bonding performance.

Recommended substrates:

• PVC and expanded PVC
• Polyurethane
• TR and expanded TR
• Neolite
• Vulcanized rubber
• Oily, semi-oily and waxed leathers
• Textiles and canvas
• Crepe
• Wood
• EVA
