Ridgefield, Connecticut - Global Matrechs Inc has gained an initial order for HNIPU (hybrid non-isocyanate polyurethane), or "Phazerthane," through its partner Phazer Inc.
The initial order is from the Metropolitan Transit Authority's (MTA) Triborough Bridge And Tunnel Authority of New York City, New York. This pilot order may become the approved product for all future coatings, which "could represent hundreds of thousands of square feet in HNIPU coating," the group said, in a 16 Oct statement.
The MTA unit began a long-term, $550-million programme to rehabilitate the Triborough Bridge in 1997. This body services the bridges and tunnels, and is in the process of upgrading and improving its facilities.
The New York State Department of Transportation says the entire Triborough Bridge complex carries about 200 000 vehicles a day between Queens, Manhattan and the Bronx. Two spans of the bridge, colourfully named 'Hell Gate' and 'Bronx Kills' are part of Interstate-278, "the only road that runs through all five boroughs of New York Citym" said the statement.
Global Matrechs president and ceo Michael Sheppard said the company is pleased with this "first order from the well-known Triborough Bridge and Tunnel Authority." The company is waiting for feedback from the use of its product and said it "believes that this could be a long-lasting business relationship."
HNIPU is a material that "exhibits superior resistance properties to chemical degradation," the company claims. In chemical resistance it is "30-50 percent better than conventional polyurethanes and has significantly reduced permeability, three to four times less," the company said.
Unlike conventional polyurethanes, which are porous, NIPUs form a material with practically no pores, said Global Matrechs. Also, the absence of isocyanates means that HNIPU binders can accept fillers without special drying procedures.
Other advantages are that, "Synthesis and use of HNIPU do not require special health protection procedures that are normally associated with the use of conventional polyurethanes, since HNIPU does not contain toxic isocyanates," the company stressed.
