LeesonBound® Technology has been confirmed through independent testing, Best-In-Class strength AGAIN!
Flexural testing, which determines the strength of a material product, was performed on LeesonBound® PU4844 7.5kg system along with a number of Leeson Polyurethanes’ competitors’ similar systems. The results demonstrated that the strength quality of LeesonBound® performed significantly better, making it the outstanding choice on the market.

The Technicians at Leeson Polyurethanes are committed to continually testing their products to check the performance standards and quality. To measure the strength of the PU4844 LeesonBound system in comparison to others available on the market, flexural testing was performed using a three-point bend testing method (see illustration above) on cured test specimens of polyurethane and aggregate. To independently verify the results obtained during the in-house testing, samples were sent to an independent laboratory which specialises in chemicals and materials analysis and backed by experienced impartial professionals who hold the ISO 17025 UKAS accreditation.
The laboratory were sent unmarked samples of PU4844 and several resembling resin systems which were prepared to identical sizes using exactly the same aggregate (as different aggregates can have different strengths), thereby the only variable being the resin. The lab used a universal testing machine and, under the same conditions, tested each sample and recorded the results. The report concluded that the LeesonBound® PU4844 7.5kg system performed the best, being almost twice as strong as its competitors.

What this means for the installer is the confidence that LeesonBound® PU4844 is of the strongest quality, and this has been independently and professionally verified. In turn, the customer will have the assurance that they are paying for a product to be installed that is durable and robust enough to cope with heavy trafficking without cracking or breaking up.
