Polyurethane Binders

Here at Synthetic Grass & Rubber Surfaces Australia Pty, we like to make sure our clients are provided with as much information as possible when looking at installing Rubber Wetpour.

When installing Rubber Wetpour there are two different Polyurethane Binders used.

Here is a simple explanation of two types of Polyurethane Binder and how these are used in rubber wetpour installations .


Aliphatic Polyurethane Binder (MDI)

  • Premium grade, non- yellowing Polyurethane.
  • It offers exceptional chemical resistance
  • Good weathering properties and super adhesion.
  • Most commonly used for wet play and splash areas
  • Aliphatic Polyurethane binder does however cost more than the Aromatic Polyurethane binder


Aromatic Polyurethane Binder

  • Most commonly used Polyurethane Binder for the installation of Rubber Wetpour surfacing, because of its economic value and availability in the market.
  • Offers flexibility and longevity
  • This particular binder is prone to yellowing due to the UV light intensity in the Australia climate. The yellowing effect will cause some colours of EPDM Rubber Granules to change momentarily until the yellowing wears off.

Here is an example of Before and After shot of the Yellowing Effect that can take place

If you would like to discuss further about the two types of Polyurethane Binders used for Rubber Wetpour installation, please contact one of our friendly staff or phone 02 9986 1133.

We look forward to speaking to you about how we can best suit your specific requirements and budget for your next project.
