STORAGE AND SHELF LIFE

IOTA 1098 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 1098 should not be applied:

As structural sealant;

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

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℃;

To porous substrates such as stone, concrete before confirmation with manufacturer.

HOW TO USE

Surface Preparation

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

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 1098 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.
