STORAGE AND SHELF LIFE

IOTA 995 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 995 should not be applied:

To 4-sided and 2-sided curtain walls;

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℃;

For metal coated glass glazing.

 

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

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 testing is always recommended.

Apply IOTA 995 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.
