This new generation Si QAC microbial control and protection treatments are very different in their mode of action to most chemical and metals based antimicrobial compounds. When Fresche treatments are applied, they form covalent associations which "lock and bond" the active molecule to the surface or substrate being treated.
Once bound to a surface or substrate, the antimicrobial coatings will not leach, migrate or otherwise leave the surface
During drying of the solution, the active ingredient changes from a monomer to a polymer, and bonds to the surface. Once bound, the Fresche molecule delivers durable, continuous and persistent protection from microbial colonisation or attack.
As a bound molecule, it delivers continuing long term microbial protection for indefinite periods of time
, unless removed from the surface by heavy abrasion and will bond to many surfaces and substrates
. The surface bond is durable and capable of providing high levels of microbial protection and control for long periods of time.
These antimicrobials can be applied to a diverse range of substrates which include:
- natural and synthetic textiles
- urethane foam substrates
- fibre fill
- various plastics
- most metals (including stainless steel)
- rigid foam
