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 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℃

 

HOW TO USE

Surface Preparation

Clean all joints removing all foreign matter and contaminants such as oil, grease, dust, water, frost, surface dirt, 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 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
