FAQs

1. What is water based leather adhesive used for?

Water based leather adhesive (like Supex 309) is used for bonding leather to leather, fabric, foam, PVC, wood, and other materials in footwear (shoes, soles), leather goods (bags, belts, wallets), upholstery (sofas, car seats), and crafts. It provides strong, flexible, eco-friendly bonds without harmful solvents.

2. Is Supex 309 water based leather adhesive solvent-free and eco-friendly?

Yes, it is solvent free ( being water based ) and it is labelled as “eco-friendly,” “environmentally safe,” and “green,” it supports sustainable manufacturing, reduces environmental impact, and is fully REACH compliant for lower ecological footprint.

3. How to apply water based leather adhesive (spray/brush)?

• Spray method (preferred for uniform coverage): Use a spray gun. Hold 20–30 cm (about 0.2 m) from the surface. Apply a thin, even coat to both surfaces in light, overlapping passes. Multiple thin layers work better than one thick one.
• Brush/roller method (ideal for smaller jobs): Use a brush or roller to spread a thin, even layer on both surfaces.

4. Advantages of water based leather adhesive over traditional glues?

1. Zero VOCs & Solvent-Free → Completely safe for workers, no toxic fumes, non-flammable.
2. Eco-Friendly & REACH Compliant → Green choice, reduces environDrying time and bond strength of Supex 309 water based adhesivemental impact.
3. No Odour → Pleasant workplace, ideal for indoor production.
4. Easy Cleanup with Water → No expensive thinners needed.
5. Sprayable & Brushable → Uniform thin coats, less wastage, faster application.
6. Strong & Flexible Bonds → Matches or exceeds solvent glue strength with better heat resistance.
7. Safer Storage & Transport → Non-hazardous classification cuts logistics costs.
8. Health Compliant → Perfect for export brands requiring low-VOC certification.

5. Drying time and bond strength of Supex 309 water based adhesive?

• Drying/Tack Time: Quick tack achieved within a few minutes (light-pressure bonding possible shortly after application). It dries rapidly, ideal for high-speed production lines.
• Full Cure Time: Typically within 24 hours, depending on humidity, temperature, and application thickness. Gentle heat (50–60°C) can accelerate and enhance the bond.
• Bond Strength: High bond strength with strong, durable, permanent bonds. It offers excellent heat resistance (up to 80°C in some references), high initial grip (especially when sprayed), peel resistance, and flexible yet tough performance that withstands stress without cracking or peeling over time.
