Product Description

Corwrep VES is a visco elastic, high tack, self-healing, highly flexible, one single product material, which is suitable for the protection and rehabilitation of pipelines and girth welds.
Corwrep VES, a solid polyolefin coating in roll form, is also used for the protection of ground outlets and piping through embankments. Minimum required cleaning grade is a hand tool cleaned St2 surface (i.e. wire brush, sandpaper). Corwrep VES is a lining system which always requires a finishing layer. This finishing could be a Corwrep PVC or Corwrep FLS layer. CMP Fibalite also advises to use a primer layer to protect the substrate for further corrosion with the 2K coating Alucemp. Alucemp has a high corrosion ability due to rust inhibitors. This all together ends up in a full protection system.
