Abstract
A biocidal additive formulation comprises a silver containing glass particle, and a combination of at least two metal based compounds. A metal in each of the metal based compounds is selected from the group consisting of silver, copper, zinc, mercury, tin, lead, bismuth, barium, cadmium, chromium, titanium, and a combination thereof. Another biocidal additive formulation comprises a silver containing glass particle, ZnO, and Bi2O3. A glass substrate possessing a durable biocidal property and an article possessing a durable biocidal property are also provided.
Claims14
A biocidal additive formulation comprising:
- a silver containing glass particle,
- ZnO, and
- Bi2O3,
- wherein Bi2O3 is present in an amount of 25% to 85% by weight based on the dry weight of the formulation.
A method for making a biocidal glass, the method comprising:
- adding a biocidal additive formulation comprised of a silver containing glass particle and at least two metal based compounds as an additive package to a glass batch formulation,
- wherein the at least two metal based compounds are ZnO and Bi2O3, and Bi2O3 is present in an amount of 25% to 85% by weight based on the dry weight of the biocidal additive formulation.
A glass substrate possessing a durable biocidal property comprising a biocidal additive package having a biocidal additive formulation comprising:
- a silver containing glass particle,
- ZnO, and
- Bi2O3,
- wherein Bi2O3 is present in an amount of 25% to 85% by weight based on the dry weight of the formulation.
An article constructed, in whole or in part, of a glass substrate possessing a durable biocidal property, the article comprising a biocidal additive package having a biocidal additive formulation comprising:
- a silver containing glass particle,
- ZnO, and
- Bi2O3,
- wherein Bi2O3 is present in an amount of 25% to 85% by weight based on the dry weight of the formulation.
