Areas of application
CM PU FC 40 can be used either for bonding various construction materials or as a sealing joint. It has excellent adhesion, without primer , on most construction materials: wood, anodized aluminium, polyester, glass, concrete, stone, concrete roof tiles, ceramic tiles, etc. It’s principle application is sealing expansion joints in concrete floor joints and saw cut joints . It is used in warehouses and external forecourts. This product is fuel resistant but not if immersed for long periods. For difficult materials, including plastics such as PVC, ABS, PMMA, or materials such as raw aluminium, lacquered metal, preliminary tests are mandatory to determine whether a surface preparation is necessary.
