Microbiocidal Paint Developed


PPG Industries has joined with Corning to develop coatings capable of destroying bacteria and viruses on contact.  The active ingredient is copper in the form of Cu+1 For stability, the copper is in the form of an alkali copper-aluminoborophosphosilicate ceramic material that serves as a delivery system for copper ions.  Available as a latex-based paint, the product is been shown to retain activity, despite frequent washing for up to five years and will meet the 99.9 percent kill standard imposed by the EPA.  Publications in peer-reviewed journals demonstrate efficacy against Staphylococcus, Pseudomonas, Klebsiella and Escherichia.


Marketed under the Guardiant™ brand, the pale blue-green powder will be available in a variety of paint colors through PPG Industries Technology.


The germicidal paint has applications in the poultry industry especially in hatcheries, processing plant break rooms and laboratories.
