The anti-viral layer in our tanks is thermostable, meaning it can withstand high temperatures without losing its effectiveness. The active copper in the inner layer is non-leachable, meaning it cannot be easily washed out or affected by normal exposure to humidity, moisture, or sunlight. Its anti-viral and anti-bacterial properties remain intact under typical environmental conditions. However, it's important to note that any structural damage to the tank's surface caused by chemical or physical treatment may impact the overall performance and properties of the product.
