STORAGE AND SHELF LIFE

IOTA 882 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 882 should not be applied:

For structural glazing;

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

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, old sealants, surface dirt, or glazing compounds and protective coatings.

Mixing and Dispensing

To obtain the optimal performance of IOTA 882, it is recommended that base and curing agent thoroughly mixed using a two-part silicone dispensing machine.

IOTA 882 should be mixed at a ratio of 9:1～11:1 base to curing agent by volume, or 11:1～13:1 base to curing agent by weight for optimal performance.

Lot matching of IOTA 882 base to curing agent is not required. Before use, it is recommended that curing agent be stirred to ensure the homogeneity of all components.

IOTA 882 part B curing agent will react with atmospheric moisture, therefore should not be exposed to air for prolonged periods of time.
