Water storage articles made from plastic polymers are susceptible to aquatic microbial colonisation. These aquatic microbes breed and accumulate on the plastic surface, leading to staining, malodour, plastic degradation, and water contamination. Protection of the water storage tanks from microbes can be achieved by integrating antimicrobial technology proven to resist their growth. N9 Plastix Silklear Plus technology works to provide antimicrobial protection in addition to increasing the durability of water storage tanks.
