Thin waterbased glue provides both excellent bonding and easy removal! Normally with waterbased glues the glue is very difficult to remove from the blade and songe. But with the unique new formula of Syncro BTG ( Bond Technology Glue ), these problems are over! Syncro BTG contains a unique combination of rubber and glue that is thin, soft, and flexible. It spreads very easily in a attachment, but when it is time to remove the rubber from the blade, the glue and rubber come off very easily. Syncro BTG is available in both 100ml with sponge and 150ml with brush.
