Fresche EF4850 contents:

50% active 3-(Trimethoxysilyl) propyl dimethyloctadecyl Ammonium Chloride in a non flammable solvent.


Fresche EF4850 will form a durable antimicrobial film covering excellent broad spectrum anti- bacterial and anti-fungal protection to a wide range of surfaces including textiles, poly- urethane foam, plastics, car seats, furniture, metals, carpets and cotton. When properly applied EF4850 creates a bacteriostatic, fungistatic and algistatic surface using only a minimal amount of additive.


Surfaces, fabrics and other textiles treated with EF4850 are safe for human contact and friendly to the environment. The antimicrobial agent is leach resistant, non-migrating and importantly is not consumed by micro organisms.


This product does not contain any organotin’s or other organo-metallic compounds. EF4850 can also be particularly suited to some urethane foam applications requiring a lower hydroxyl value.
