Pittsburgh, Pennsilvania - Miami-Dade County's Building Code Compliance Office has certified a spray polyurethane coating from Bayer MaterialScience llc for use as a roofing material in a high-velocity hurricane zone. T
"Contractors and applicators looking for a long-lasting spray coating system that can take what Mother Nature dishes out can rely on Baytec SPR 185A FR thick film coating," commented Mike Hurley, development scientist, BMS, in a company announcement.
BMS said the thick spray system, formulated specifically to protect metal or concrete industrial roof systems, is one of many such coatings approved by federal, state and local authorities as well as civil engineering and consulting firms in the US and worldwide.
For example, Baytec SPR 185A FR thick-film coating recently passed Underwriters Laboratories Inc.'s UL790 test for fire resistance of roof covering materials.
Hurley said the spray system combines durability, flexibility and rapid cure to create a monolithic, seamless roof coating with "exceptional protection against leaks, weathering and foot traffic."
The group claims its spray PU membranes have been applied and in-service for more than 30 years in demanding environments around the world, standing up to to demanding environments, while resisting ozone, hydrolysis and many chemicals. Baytec SPR spray systems even pass the Ponding Water Test where other roof coatings fail.
