A small but significant stepHealth Canada's thumbs up obviously validates Zen's graphene coating technology. Its application is clearly for masks but also for filter systems. That, in itself, is a significant market and let's not forget that Zen did previously indicate that it had been contacted by many businesses, domestic and abroad about its coating technology. There is a decent chance that today's development is just a first step of success in Zen''s portfolio of graphene technological applicaitons (and there are many that don't involve coating). It is also significant that Zen got Health Canada's approval for Zen's reputation as a credible company. I'm waiting patiently for more contracts and more applications of Zen's garaphene, followed by more contracts rekatubg to these new applicaitons. Its also reasonable to believe that as a result of its coating technology, Zen's treasury will be significantly enhanced. That should accelerate developments for the company..
