Corning® Guardiant® is a breakthrough antimicrobial powder additive that can be mixed into paints, coatings, and plastics to impart continuous, long-lasting antimicrobial efficacy. Guardiant leverages copper ion technology that enables products registered with the US Environmental Protection Agency (EPA) to provide supplemental residual sanitizing activity to kill 99.9% of bacteria and viruses within two hours of contact on a painted surface.
Antimicrobial Additive: Copper-Powered Peace of Mind
The Guardiant Advantage
Products with Guardiant provide unparalleled advantages, addressing the challenges of today as well as tomorrow. Products with Guardiant have been shown to:
- kill a broad spectrum of bacteria and viruses, including the virus that causes COVID-19
- work continuously with high potency to kill >99.9% of bacteria and viruses in two hours or less
- provide long term antiviral and antibacterial activity
- maintain high efficacy under international testing standards and newer testing methods to simulate realistic conditions
Where Can I Use Guardiant as an Additive?
Corning works closely with our customers to develop products with Guardiant-powered antiviral (virucidal) and antibacterial capabilities to benefit homes, hospitals, schools, and more.
Applications
PAINT
Paints powered by Corning Guardiant have been proven to kill bacteria and viruses up to 6 years after the initial application of the paint – which is perfect for high traffic sites such as hospitals, classrooms, and offices.
COATINGS
High-traffic areas such as locker rooms and public tranportation facilities can benefit from coatings featuring Guardiant.
PLASTICS
Plastic materials protected with Corning Guaridant can offer enhanced protection for a wide variety of high-touch surfaces including phone cases, health care products, or products for educational settings.
Consumer Products
FLOORING
Floors in high-traffic areas can benefit from Guardiant’s antimicrobial technology – offering peace of mind for those entering and exiting a facility.
COUNTERTOPS
Guardiant’s continuous germ-killing capabilities are an excellence feature for frequently utilized countertops for residential, industrial, and health care uses.
MOBILE CONSUMER ELECTRONICS
Phone cases designed with Corning Guardiant can offer antimicrobial protection for devices used in our daily lives.

鉴于当前全球面临的健康问题，我们深刻意识到，细菌和病毒往往潜伏于我们身边的各类表面上。即使采取了定期洗手和对所接触的表面进行消毒等一系列措施，但我们仍无法确保自己和家人能时刻免于病菌侵扰。
如果二次污染频繁发生，我们是否也该采取具有长效性的消毒手段？
Corning Guardiant™ 是一款新型抗微生物添加剂，其可被加入到涂料和涂层配方中，从而激活我们身边涂层表面的杀菌功效（如墙壁和家具）。第三方实验室根据美国国家环境保护局 (EPA) 所批准的测试方法进行的实验结果表明，含有Corning Guardiant的涂料在实验室条件下，能在两小时或更短时间内杀灭涂层表面超过99.9%的特定细菌和病毒1。

激活成为抵御细菌和病毒的额外防护。
Corning Guardiant™ ：利用铜的抗微生物特性
众所周知，铜及其合金具有抗微生物功效。几个世纪以来，我们的生活始终离不开含铜产品，如铜质水管和厨具。
康宁的研究人员研制出一种新的玻璃陶瓷组分，能稳固铜最活跃的抗微生物价态——正一价铜离子 (Cu+1) 并发挥其功效。将含铜的玻璃陶瓷研磨成非常细小的颗粒，Corning Guardiant添加剂由此诞生。这款添加剂不仅能起到保护涂层的作用，还能持续减少涂层表面特定的有害细菌和病毒1。Corning Guardiant利用铜的抗微生物功效活化表面，同时没有金属铜外观和属性的限制。
在美国国家环境保护局 (EPA) 批准且模拟现实污染环境的测试方法下，含有Corning Guardiant的涂料能在两小时或更短时间内杀灭涂层表面超过99.9%的特定细菌和病毒。含有Corning Guardiant的涂料即使经过（实验室模拟现实环境）六年以上时间的清洁和擦洗，也能维持抗微生物功效。2
我们在行业内的权威期刊《自然通讯》上进一步解释了Corning Guardiant™ 这项发明背后的原理。
