Chinese national specification.
GB/T 14683-2003 20HM.
SHELF LIFE
It has a shelf life of 12 months from the date of manufacture.
LIMITATIONS
GB 557 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 GB 557 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.
