    Surface Preparation


    Recommended Substrate Conditions and Temperatures

    Substrate conditions

    • Previous coat must be dry and free from any contamination

     

    Substrate Temperature & Application Conditions


    • Substrate temperature during application and curing should be above -5°C (23°F)
    • Substrate temperature during application and curing down to -5°C (23°F) is acceptable; provided the substrate is free from ice and dry
    • Substrate temperature during application and curing should be at least 3°C (5°F) above dew point

    Application


    Instructions for Use

    Mixing ratio by volume: base to hardener 86:14

    • The temperature of the mixed base and hardener should preferably be above 15°C (59°F), otherwise extra thinner may be required to obtain application viscosity
    • Adding too much thinner results in reduced sag resistance and slower cure
    • Thinner should be added after mixing the components

    Notes:

    • Adequate ventilation must be maintained during application and curing (please refer to information sheets 1433 and 1434)
    • In exceptional cases SIGMACOVER 555 may be applied at lower substrate temperatures (down to -15°C (5°F)) provided that the surface is free from ice and other contamination. In such cases special care must be taken to avoid thick film application as this may lead to checking/crazing or solvent entrapment. It should be clear that application at lower temperatures will require additional thinning to obtain application viscosity, however this will affect the sag resistance of the applied coating and can induce solvent retention. Optimal curing and designed product properties will only be achieved when minimum required substrate temperature is reached

    Safety Precautions


    • For paint and recommended thinners, see information sheets information sheet 1430, information sheet 1431 and the relevant Material Safety Data Sheets in the attachments section above
    • This is a solvent-borne paint and care should be taken to avoid inhalation of spray mist or vapour, as well as contact between the wet paint and exposed skin or eyes
