Cleanroom Suitable Materials

Manufacturing under cleanroom or clean conditions is essential for a growing number of industries in order to safeguard process operations and the quality of components.

A cleanroom is defined as a controlled environment that has a low level of pollutants including dust, airborne microbes, aerosol particles, and chemical vapours.

Two of Flowcrete’s epoxy based floor and wall coating systems are now able to better demonstrate their suitability for use within cleanroom environments having qualified as Cleanroom Suitable Materials under the Fraunhofer Institute for Manufacturing Engineering and Automation (IPA).

Both Flowshield SL - a colourful, high-gloss, self levelling epoxy floor coating and Flowseal EPW Wall - a pigmented, hygienic epoxy based wall sealer have met the requirements of a number of cleanroom standards set out by the IPA in accordance with the CSM test parameters.

Under testing, Flowshield SL exhibited excellent biological resistance (inert and fungi static) in accordance with ISO 846. Emissions of TVOC (Total Volatile Organic Compounds) at 23°C did not exceed the limiting values for ISO-ACCm Class-8.7 according to ISO 14664-8 and particle release under frictional stress demonstrated compliance with the air cleanliness requirements of ISO Class 4 cleanrooms according to ISO 14644-1.

Flowseal EPW Wall Sealer is a naturally coloured epoxy coating for use on both walls and ceilings, used to ensure a hygienic, easily cleaned and chemical resistant lining within clean room environments. Flowseal EPW Wall Sealer when tested for outgassing behaviour registered emissions of TVOC at 23°C not exceeding the limiting values for ISO-ACCm Class>-9.6 according to ISO 14664-8.
