Supex 309 Water Based Leather Adhesive
Supex 309 is a water-based adhesive explicitly formulated for bonding leather, PVC, foam, rexine, and other materials where solvent-based spray adhesives are typically used.
Key Benefits:
- Environmentally friendly & safe: Zero VOCs, REACH compliant, and non-flammable.
- Odour-free, creating a safer workspace with no strong fumes.
- Enables permanent, strong bonding with quick drying times — ideal for fast-paced production.
Suitable for spray application, which speeds up processing and ensures uniform coverage. Versatile substrate compatibility: Bonds materials like foam, fabric, plastic, cardboard, jute, rubber, vinyl, and porous substrates.
Additional benefits: high yield, instant bond, soft bond line, and resistance to high temperatures.

How to Apply Supex 309 water-based leather adhesive
Surface Prep
Clean both surfaces (leather, foam, PVC, etc.) from dust, oil, or release agents.
For smooth leathers, lightly roughen the surface for better adhesion.
Application
Best applied via spray gun (gives even, thin coating).
Brush or roller can work for small projects.
Bonding
Allow adhesive to tack (partially dry, no wet transfer).
Join both surfaces and apply firm pressure (hand roller, press, or hammer with cloth).
Drying Time
Quick tack: a few minutes for light pressure bonding.
Full cure: usually within 24 hours, depending on humidity/temperature.
Tips
Apply in thin coats; multiple light coats bond better than one heavy coat.
Heat activation (mild 50–60 °C) can improve bond strength.
Store tightly sealed to prevent premature drying.
