D.A.VACD.A.VAC has been operating for four years as a one-man operation working with dozens of specialists assigned by industry to the technologies being implemented. I am the owner of highly advanced Nano technologies developed for 30 years under the name of many companies that I have owned or own. Currently, I am concentrating most of the dozens of patents filed, which are practically used in the US, Canada, Mexico, Australia and most EU countries. I place special emphasis on Nano vacuum PVD technology - Antibacterial Coatings with a permanent and extremely strong biocidal effect of 99.999999% - the highest level of biocidality yet implemented in the world as a permanent coating that has been applied to food packaging films extending their shelf life.
