When first introduced in 1996, Bona Mega was an industry-first with its revolutionary oxygen crosslinking technology. It became the clear choice as a 1-component topcoat for wood floors in any environment requiring medium to light commercial or residential wear resistance.Based on this concept, Bona introduces Bona Mega EVO™, a topcoat with new state-of-the-art self crosslinking technology that activates when applied. Unlike Bona Mega, which uses oxygen as the crosslinker, Bona Mega EVO™ uses a completely new and significantly faster technology that is unique to Bona. The self crosslinking formula gives a true hardening, without the use of any external components, making it the next generation coating.
