STORAGE AND SHELF LIFE

IOTA GF999 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 GF999 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 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 protecting 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 GF999 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.
