This is a two part epoxy formulated to cure rapidly, it has a 6 minute working time, and is solid in about 30 minute at 77 degrees Farenheit, longer if cooler. You can use this material to rejoin broken, cracked or seperated plastic, as well as gouges. It is black and cures black as well. It can be sanded, painted and worked. Where this material is different from other epoxies, or epoxies geared to hard plastics and metals, is that not only does it bond to the soft plastics but is also remains flexable as well so it iwll not break out or seperate as a harder epoxy otherwise would.
