Product Information

CURE TIME

As exposed to air, SV888 begins to cure inward from surface. Its tack free time is about 50 minutes; the full and optimal adhesion depends on the sealant depth.

SPECIFICATIONS

SV888 is designed to meet or even exceed the requirements of:

● Chinese national specification GB/T 14683-2003 20HM

STORAGE AND SHELF LIFE

SV888 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

SV888 should not be applied:

● For structural glazing

● For weather seal for curtain walls

● To underground joints

● To joints with high movement

● To the materials that bleed oils , plasticizers or solvents, such as impregnated wood ,or unvulcanized resin

● 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 protective coatings.

Application Method

Mask areas adjacent to joints to ensure neat sealant lines. Apply SV888 in a continuous operation using dispensing guns. Before a skin forms, tool the sealant with light pressure to spread the sealant against the joint surfaces. Remove masking tape as soon as the bead is tooled.
