About Us – In Pursuit of a Germ-Free World

Our Vision

A world where every touchable surface is coated with XTI-360 and germ-free.


Our mission is to eliminate the contact transmission of germs from surfaces and indoor environments in order to 1) prevent the spread of illness, 2) protect our front-line and essential workers, 3) help businesses, and society in general, safely open and operate during this ongoing (and any future) pandemic and 4) help America prepare for additional waves of COVID-19, as well as future outbreaks of other diseases (some of which are already appearing around the globe).

About Us

American PPE & Coating Services, Inc. (“APPE”) and American CleanCoating Company (“ACC”) are commonly owned and operated companies formed and based in the United States of America.  APPE sells, and will soon produce in America, StaClean™ brand, FDA certified, medical face masks, coated with XTI-360, and coat other PPE and other property with XTI-360.  ACC coats surfaces in buildings, building contents (furniture, fixtures, carpeting, curtains, etc.), aircraft, cruise ships, autos, entertainment and sports venues, and all kinds of manufactured products, with XTI-360.  Our goal is to reduce contact transmission and cross-infection of virus and bacteria germs through the application of advanced technological solutions. 

We can presently provide commercial quantities of high-quality, medical masks, meeting all requirements for FDA certification (customers can specify L1, L2, or L3) and providing at least 95 percent filtration, on a monthly subscription (“auto-order”) basis.  This assures customers of timely delivery of a specified number of masks each month, at an assured price, even in times of PPE shortage and resultant spikes in market prices.  Until we can fill orders with our own, made in America, StaClean masks, all masks and mask materials sold will be from Taiwan, a United States Government recognized world leader in the management of COVID-19.  No masks or materials will be from the People’s Republic of China.  (Taiwan, with a population of nearly 25 million people, has had a total of under 10 deaths from COVID-19.)
