CURE TIME
As exposed to air, BM668 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
BM668 is designed to meet or even exceed the requirements of:
Chinese national specification GB/T 14683-2003 20HM
STORAGE AND SHELF LIFE
BM668 should be stored at or below 27℃ in original unopened containers. It has a shelf life of 12 months from the date of manufacture.
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 BM668 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.
