Vibra-Tite 910G Epoxy is a 2-part system that forms a strong bond when cured. While flowing through the mix nozzle (sold separately), the blue resin and yellow hardener combine and dispense as a solid green color, providing visual proof of a thoroughly mixed epoxy. Once applied, this material allows 4-6 minutes of positioning time and can be handled in 1 hour. This product is formulated as a gel, which makes it ideal for both vertical and horizontal surfaces.
