Contains isocyanate: requirement for full-face air assisted mask during & immediately after coating application. Low odour in application & service Atomised isocyanates pose a potential risk to coating applicators: may cause lung sensitisation with severe asthma like reaction after repeated exposure. However this is not a problem if PU is sprayed in a good quality spray booth and an external air source full face mask is worn. Formaldehyde free Excellent flexibility and therefore superior scratch and impact resistance. Coating waste will result if all catalysed (mixed Part A + B) coating is not consumed within the coating's pot life. Once the film has cured, no residual emission of toxic compounds. The longer the elapsed time period between initial mixing of Part A + B the worse the physical properties of the final coating.  Find out more about..........  MIROTHANE PU Visual Appearance  MIROTHANE PU Product Range  MIROTHANE PU In Service Performance  Other Mirotone Coatings
