G-S Hypo Cement was invented in 1939 for use in the watchmaking industries. It is a combination of a fine precision tool and a clear drying, medium-strength cement that will not damage surfaces. The cement is ideal for watch plastic glasses, bezels and watch metal part. This is a no-waste product that is ideal for many applications. Full use of the precision applicator tip is maintained by inserting the cap wire into the tube when not in use, and by cleaning excess drops from the outside of the applicator with rubbing alcohol. This is not an "instant glue." It becomes tacky in 10 - 15 seconds, allows parts to be adjusted, and dries in 10 to 15 minutes. 9ml.
