    COLOURS

    IOTA 997 is available in black, gray and other customized colours. 



    STORAGE AND SHELF LIFE

    IOTA 997 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 997 should not be applied:

    As structural sealant

    To the materials that bleed oils, plasticizers or solvents, such as oil-based caulks,impregnated wood,.

    In totally confined spaces as sealant requires atmospheric moisture for cure

    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, dust, water,grease,  frost, protective, coatingssurface dirt,.

     

    Application Method

    Install back-up materials or joint fillers, setting blocks, spacer shims, and tapes. Mask areas adjacent to joints to ensure neat sealant lines. Primer is generally not required for non-porous surfaces, but may be necessary for optimal seal performance of certain porous surfaces. So adhesion test is always recommended. Apply IOTA 997 in a continuous operation using dispensing guns. Before a skin forms, tool the sealant with light pressure to spread the sealant against the backing materials and joint surfaces. Remove masking tape as soon as the bead is tooled
