It is used as:- Crack-bridging and chemically resistant coating for concrete and screed surfaces in bund areas for the protection against water contaminating liquids (according resistance table)
- Electrostatic conductive wearing course for areas subject to chemical exposure which are likely to crack
Advantages
- High chemical resistance
- Crack-bridging
- Liquid proof
- Electrostatic conductive
Packaging
Please refer to individual Product Data Sheet.
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 sunlight 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
