This Aromatic Binder is the essential adhesive agent for creating professional-grade bonded rubber surfaces. As a single-component, moisture-cured polyurethane binder, it reacts with moisture in the air and sub-base to create an exceptionally strong and resilient bond between rubber granules. Its formulation is optimised for ease of use in a forced-action mixer, ensuring every shred of rubber is evenly coated for a consistent and reliable cure.

While incredibly strong, this binder has a natural amber hue and will darken slightly over time with exposure to UV light. For this reason, we exclusively recommend its use with our darker rubber mulch colours, where this subtle shift will go unnoticed. For a long-lasting, durable, and economical bonded rubber installation, our Aromatic Binder is the proven and trusted choice.

Aromatic vs. Aliphatic Binder: What's the Difference?

This is a crucial technical distinction based on how the binder reacts to sunlight (UV radiation). The binder you choose depends entirely on the colour of the rubber you are using. Aromatic Binder (This Product): This is the strong, cost-effective workhorse of the industry. Its one drawback is that it is not UV stable, meaning it will naturally amber or darken when exposed to sunlight. This makes it the perfect choice for dark-coloured rubber like brown, red, and black, as the subtle colour shift of the binder is unnoticeable. Aliphatic Binder: This is a premium binder that is completely UV stable. It will not amber or yellow over time, even under direct sunlight. Because it is significantly more expensive, it is reserved for projects using brightly coloured EPDM rubber granules like blue, green, yellow, orange, or beige, where colour stability and vibrancy are essential.

In short:

Use Aromatic Binder for dark rubber colours.

Use Aliphatic Binder for bright or light rubber colours.
