General-purpose cyanoacrylate glue. Fast drying, extra strong, low viscosity, specially formulated for adhesion between materials that can even have an acidic surface. Can be used with rubber, leather, wood, metal, resin and plastic. The surfaces to be joined must be free of dirt, dust and grease. A small amount of adhesive should be applied; more cyanoacrylate does not guarantee a better bond and makes more difficult the drying of the adhesive that is effective for bonding.
