STORAGE AND SHELF LIFE
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
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.
