SigaFlex 510

Low-emission, flexible, 2-component polyurethane coating

SigaFlex 510 is a low-emission, free-flow, 2-component polyurethane coating suitable for smooth, energy-elastic coatings, as well as for slip resistant scattered coatings. The coating has good flow- and smoothing properties and cures with almost no shrinkage. The cured coating is hard and tough but also flexible and resistant to mechanical load. SigaFlex 510 offers special advantages where increased flexibility is necessary due to, e.g. substrate susceptible to deformation, like mastic asphalt, flake boards, metallic and reconstruction substrate. The resistance to chemicals like water, salt solutions, diluted acids and alkalis, mineral oil, and diesel fuel is sufficient. For organic acids polyurethane coatings offer special advantages. Note: SigaFlex 510 is available in different colours. Even though due to its chemical structure the material is not resistant to yellowing. Slight colour tone alteration is possible. Please note our general recommendation on colour / colour tones. Pale colours should be additionally sealed with colour stable SigaFlex 537. Attention: Sealers are suitable only to a limited extent for forklift-traffic. Please seek advice. Indentions cannot be excluded for concentrated point load.
