    Notes:

    • See below for more information on surface preparation, application details and curing times

    Surface Preparation


    Recommended Substrate Conditions and Temperatures

    Substrate conditions

    • Compatible previous coat must be dry and free from any contamination
    • Surface of previous coat should be sufficiently roughened if necessary

     

    Substrate Temperature & Application Conditions


    • Substrate temperature during application and curing should be above 5°C (41°F)
    • Substrate temperature during application and curing should be at least 3°C (5°F) above dew point
    • Relative humidity during application and curing should not exceed 85%

    Application


    Instructions for Use

    Mixing ratio by volume: base to hardener 89.5:10.5

    • Adding too much thinner results in reduced sag resistance
    • 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
    • If required, thinner should be added after mixing the components

     

    Induction Time


    None.

     

    Pot life


    • 6 hours at 20°C (68°F)

    Note:

    • In order to achieve the optimum finish and cosmetic appearance, the product may be thinned by 10% and applied using an air-assisted airless spray gun set up with a smaller tip size of 0.28 – 0.38 mm (0.011 – 0.015 in)
