STORAGE AND SHELF LIFE
IOTA 999 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 999 should not be applied:
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 substrate surface temperature below 4℃ or over 50℃
