HOW TO USE
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.
Mask areas adjacent to joints to ensure neat sealant lines. Apply GB 996 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.
Complete technical information and literature, adhesion testing and compatibility testing are available from Guibao.
