    STORAGE AND SHELF LIFE

    IOTA 882 should be stored at or below 27℃ in original unopened containers.
    It has a shelf life of 12 months from the date of manufacture.

     

    LIMITATIONS

    IOTA 882 should not be applied:

    To the materials that bleed oils, such as impregnated wood, plasticizers or solvents, oil-based caulks;
    For structural glazing;

    To frost laden or damp surfaces;

    For continuous water immersion;

    When surface temperature below 4℃ or over 50℃

     

    HOW TO USE

    Surface Preparation

    Clean all joints removing all foreign matter and contaminants such as oil, water, frost, grease, dust, old sealants, surface dirt, or protective coatings and glazing compounds.

     

    Mixing and Dispensing

    To obtain the optimal performance of IOTA 882, it is recommended that base and curing agent thoroughly mixed using a two-part silicone dispensing machine.

    Lot matching of IOTA 882 base to curing agent is not required. Before use, it is recommended that curing agent be stirred to ensure the homogeneity of all components.
    IOTA 882 should be mixed at a ratio of 9:1~11:1 base to curing agent by volume, or 11:1~13:1 base to curing agent by weight for optimal performance. 

    IOTA 882 part B curing agent will react with atmospheric moisture, therefore should not be exposed to air for prolonged periods of time.
