bio shield techBio Shield Tech announced it has improved the formula for its Silver Bullet AM, a shop-applied anti-microbial coating.

“Today, there is an unprecedented demand for cleaner anti-microbial-protected ductwork in our buildings,” said Bio Shield Tech spokesman Jeff Drucker.

The new formula still includes germ-fighting Agion silver ions, and new copper compounds that fight the formation of mold, mildew and algae in HVAC systems.

The new Silver Bullet AM is available in silver, black and clear.
