Moisture Cure Polyurethane Binders

Moisture Cure Polyurethane Binders are used on polymeric surfaces and impact absorbing playground surfacing areas. The PU binders have been used for years as adhesives for varnishes, sealers and in the domestic market. It is a moisture curing adhesive that pulls liquids from the air with the humidity and hence the reason is has to be used in the correct weather conditions. 

What is Polyurethane?

Information from Wikipedia: Polyurethane (PUR and PU) is a polymer composed of organic units joined by carbamate (urethane) links. While most polyurethanes are thermosetting polymers that do not melt when heated, thermoplastic polyurethanes are also available.

Polyurethane polymers are traditionally and most commonly formed by reacting a di- or poly-isocyanate with a polyol. Both the isocyanates and polyols used to make polyurethanes contain, on average, two or more functional groups per molecule.

How Does Polyurethane Binder Work?

The water molecules from the atmosphere that gives the humidity is what makes the resin set and you on average have one hour playing time during installation to be able to work with the binder adhesive. Once the polyurethane moisture cure binder is let into the open then it quickly starts to cure and for it to be full cured takes approx 24-48 hours before people can walk on the area.

We ensure that we take great care when using this product for any of our services, as we understand that it must be applied properly and with meticulous attention to detail so that the finished product is of the highest standard possible.

Polyurethane Binder for Playgrounds

The mix of the PU binder is done with rubber epdm chippings for the wetpour surface and SBR rubber crumb for the base layer wet pour safety surface. It is mixed in a continuous rectangle mixer on site and installed insitu which gives the benefit of being able to be laid to any depth, shape and size.
