Pure-spacesuited water vapor diffusionable ground coating

Particularly with new buildings the requirement often exists that due to close time schedules grounds are to be coated, without the concrete or Zementestrich drained on the humidity suitable for usual coatings. With StoPox wl 100 from there a ground coating from a water vapor diffusionable aqueous epoxy resin was examined with Fraunhofer IPA, Stuttgart, for its pure space fitness. With a high nuclear dampness of the concrete or with surfaces lying against soil the humidity can diffuse as water vapour by the coating, so that no humidity-conditioned blisters and/or damage can develop. The result of the Reel on disk test, with which a mechanical load takes place via a PP wheel, certifies the fitness for the employment in a pure area of the ISO class 4 in accordance with ISO 14644-1 bzw.GMP class A in accordance with EC GMP annex 1, in operation. Likewise the coating is characterised by very small emissions (outgassing). Likewise the examination effected with Fraunhofer IPA certifies TVOC (23�C/90�C) -9.6 in accordance with ISO 14644-8.�
