PU5541 is an aliphatic polyurethane prepolymer encapsulation binder for use with for example Leesonmix stone blend as a pebble effect floor coating or tree pit infill. PU5541 is based on aliphatic polyurethane technology to give enhanced UV performance.
PU5541 can be used with any of the approved stone mixes tested in our laboratory. If alternative aggregates are required, we offer a UV strength testing service at our laboratory. We strongly urge our customers to make use of this service prior to installing with an unapproved aggregate.
