Summary:Historically corrosion protection has been achieved through use of hexavalent chromium ions along with heavy metals in paints. These chemical ingredients are highly toxic to environment and human health. In-fact, Hex-Chrome is a known human carcinogen. DoD and commercial market is aggressively looking for safer alternates. EPA in USA and REACH regulation is Europe have already posted sun-set date for the use of toxic hex chrome and other harmful ingredients in paints. On the other hand, human health is severely affected by infection through bacterial attacks. For example, in an aircraft, that is operating globally, bacteria can remain on surface of cabin for weeks. The global coating market is expected to grow to $176B by 2020 and by next year, the US environmental friendly coating market will be $117B; while the US corrosion protection coating market will be $30B by 2021. So obviously, there is a huge demand of environmental friendly coatings to combat corrosion and microbial activities. There are more than 23,000 commercial aircraft in operation that need protection from corrosion and aggressive microbial activities. Our company Flora Coatings has developed an environmental and user friendly, transparent, ready to use (no mixing needed), multifunctional, quasi-bioceramic, flexible coating to act as a barrier against corrosion and microbial activities. This liquid coating can be applied easily in ambient conditions and cures in ambient conditions without the need of external heating. It can act as a standalone coating, a primer as well as a topcoat for the existing surface paint & coatings.
