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.

Finding the Right Antimicrobial Paint
Finding the Right Antimicrobial Paint
Choosing from different antimicrobial surface technologies can be challenging. Follow this easy 3-step guide on what to look for when selecting an antimicrobial paint.
What to Look For
EPA Registration
EPA Registration # on the Label
Read MoreLook for an EPA registration on the label, and the words “kill” or “reduce” when it comes to microorganisms. This indicates the product has gone through the necessary registration with the US Environmental Protection Agency and is demonstrated to actively kill bacteria.

Longevity
Longevity
Look for a claim about the longevity of the paint's antimicrobial capability. This will indicate the useful life of the paint's efficacy against bacteria.

Viral Efficacy
Viral Efficacy
Look for claims against “Feline Calicivirus”, Norovirus or another non-enveloped virus. Some antimicrobial ingredients only work against easier-to-kill germs, so it's important to check the fine print to be certain the product is effective against hard-to-kill microorganisms like non-enveloped viruses.

用于涂料和表面涂层的新型抗微生物添加剂，悄然守护您的健康
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。

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
