Coating systems for cleanrooms and clean manufacturing areas

Manufacturing under cleanroom or clean conditions is essential for a growing number of companies, in order that they can safeguard their process operations and the quality of their components.

The requirements of the various industrial sectors differ significantly. Cleanrooms and clean manufacturing areas are used primarily in the following industrial sectors:

Cleanrooms

  • Semiconductor industry
  • Photovoltaics
  • Microsystem technology
  • Food industry
  • Pharmaceutical industry
  • Biotechnology
  • Aviation and space industry

Clean manufacturing areas

  • Automobile and supplier industries
  • Machine engineering

Equipment, which also includes the floor, wall and ceiling coatings, has a significant influence on the room air quality. The different requirements and the necessary properties of the coating systems for these are described below.

Coating systems based on epoxy resin are ideally suited to the requirements of cleanrooms. They have proven themselves primarily due to their smooth surface and very good chemical resistance. They also have very good abrasion performance and therefore very low particle formation, when subjected to mechanical stress such as for example contact with persons or vehicles.

The outgassing behaviour has also been further improved in recent years due to targeted selection of material ingredients as part of the development of the products. The latest generation of epoxy resin dispersions or emulsions contain only water and hardly any share of volatile components.

Coating systems generally consist of the following work stages:

  • Substrate preparation
  • Primer
  • Levelling layer
  • Finishing coat

It is strongly recommended, that test surfaces are created in advance of the work, so that a picture of the edge zone of the concrete is formed. Depending on the concrete quality and the quality level of the installation, this can be very variable as regards suction behaviour, surface tensile strength, roughness and frequency of pores and shrinkage holes.
