Product Information Sheet:


ROCKBOND CRACK INJECTION T GROUT (RB CITG) is an unique two part, solvent free, epoxy resin system which consists of a hardener and a base resin.  When the hardener is mixed with the base component, a thixotropic gel is produced which gradually hardens to produce a white, strong bonding, low modulus, flexible adhesive used for the filling and sealing of cracks, gaps and voids.  The material is also used to bond concrete to steel, and many other construction materials, including stone, brick, plastic, glass and wood.  The resin is supplied in 480g/400ml and 3.6kg/3 litre packs and has a shelf life of 2 years.
