CURE TIME
As exposed to air, GUIBAO 999 begins to cure inward from surface. Its tack free time is about 60 minutes, the full and optimal adhesion forms in about 21 days.
LIMITATIONS
GUIBAO 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℃.
