Usage

It is used as:
  • Chemically highly resistant coating for concrete and screed surfaces in bund areas for the protection against water contaminating liquids (contact Sika technical service for specific information)
  • Electrostatic conductive wearing layer for areas subject to chemical and mechanical exposure in production and storage facilities

Advantages

  • Very high chemical resistance
  • High mechanical resistance
  • Impervious to liquids
  • Abrasion resistant
  • Electrostatically conductive
 

Packaging

Colour

Almost unlimited choice of colour shades.

Due to the nature of carbon fibres providing the conductivity, it is not possible to achieve exact colour matching. With very bright colours (such as yellow and orange), this effect is increased. Under direct sun light there may be some variations and colour variation, this has no influence on the function and performance of the coating.

Appearance

Self-smoothing system – gloss finish

15-20°C: 1 : 0.1 pbw;
20-30°C: 1 : 0.2 pbw

These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level or wastage etc.
*All values have been determined using quartz sand F 34 (0.1–0.3 mm) from Quarzwerke GmbH Frechen. Other quartz sand type will have an effect on the product, such as filling grade, levelling properties and aesthetics. Generally, the lower the temperature the less the filling grade.
