1. Concrete masonry stone steel wood and FRP 8 C 35 C CSE Standard is a two component low viscosity structural epoxy adhesive specifically designed for low pressure injection using automatic meter mix and dispensing equipment suitable for the CHIP system Primary uses include the structural repair of cracks voids interstices and delaminations in concrete masonry stone sealed wood and FRP filling of porous and honeycombed concrete and grout adhesive bonding of steel and fibre reinforced plastic external reinforcement anchoring bolts dowels and rebar into concrete Features Limitations Packaging Storage Chemical resistance Color Application Preparation CSE SALES AG masonry or stone Applications requiring material thickness in excess of 6 mm may be facilitated by pre placing aggregate in the void CSE Standard bonds to dry damp and wet substrates The components do not contain volatile organic compounds VOC s and are solvent free The physical properties of the product allow its use in applications requiring resistance to creep and stress relaxation maintenance of mechanical properties at high ambient temperatures high load bearing strength and excellent adhesion under adverse application conditions eg cold wet concrete Unlike many other high modulus epoxy adhesives CSE Standard cures to a tough resilient polymer and has excellent load transfer capability Depending on the application tempera2. from the next adjacent port sealing of the injection port and continuation of injection in the adjacent port shall continue until the crack is filled The process of injection may be modified to the extent that injection at the original port may be continued after emergence of adhesive from the adjacent port by sealing that port and waiting for emergence at the next port or ports This modification of the regular injection procedure may be used if the injection pressure does not substantially increase the port seals remain in place and no leaks become apparent If port to port travel of the injection adhesive is not indicated the work shall be stopped and remedial action shall be taken which may require resetting of surface ports Such work shall only be done after authorization Cure Finishing CSE SALES AG from the responsible engineer After the crack has been completely filled the injection adhesive shall be given sufficient time to cure generally at least eight hours depending on the curing conditions a significantly longer period may be necessary to a state which allows removal of the seal without any adhesive run out or smearing of the adjacent surface All surface seal material and injection adhesive runs or spills shall be carefully removed from the surface if so directed by the responsible engineer The face of the repaired crack shall be finished flush with the adjacent surface and indentations or protrusions caused by
