Droplet glue is used to repair all kinds of materials such as ceramics, wood, metal, rubber and porcelain. It is very easy to apply and only one Drop is enough To open the tube with the Droplet for the first time, screw the dispenser connected to the screw cap onto the thread of the tube until the membrane is pierced. Do not squeeze the tube too tightly so as not to spill the glue. By applying a small amount, you will get a better bond and the glue will set faster.  The droplet® does not glue polyolefins (polyethylene and polypropylene), Teflon (PTFE), EVA rubber, or silicone. https://youtu.be/JaNv1jaOaIY
