DYWIDAG Corrosion Protection System DYNA Protect
Perfect corrosion protection is an essential precondition for the durability of steel parts. This applies to an even greater extent to tension members which are exposed to dynamic loads.
DSI has developed the DBGM-patented corrosion protection system DYNA Protect ® for tension members with metallic surface such as stay cables or bracings.
This system can be used both for new construction and for structures that are already in use.
Corrosion Protective Tapes
| The corrosion protective system DYNA Protect is based on the corrosion protective tapes DYNA Protect-B and DYNA Protect-C which have been derivated from the butyl rubber tapes established by DENSO GmbH, Leverkusen, more than 40 years ago. | These tapes were optimized especially for this application. In the overlap area between the single layers, the butyl rubber compound adheres by cold amalgamation. | Thus, a closed, tubular, mechanically highly resistant and stable coating is formed which is practically impermeable to water vapor and oxygen. | |
| DYNA Protect-B: | 3-ply tape consisting of a stabilized polyethylene carrier film which is coated on both sides with a duroplastic butyl rubber based compound. |  | butyl rubber polyethylene carrier butyl rubber |
| DYNA Protect-C: | 2-ply tape consisting of an outer colored polyethylene carrier film which is coated with a butyl rubber based compound on one side. Standard colors are white, yellow and black. Other colors are available on request. |  | polyethylene carrier butyl rubber |

Layout of the Corrosion Protection System DYNA Protect
| The corrosion protection tape DYNA Protect-B is applied on the mechanically cleaned cable surface. The corrosion protective tape DYNA Protect-C is | wrapped around the corrosion protective tape DYNA Protect-B. Both tapes are wrapped with an overlap of 50 % each. Thus, a 3-layered, locked butyl rubber coating with a colored | polyethylene surface is produced. The total thickness of the corrosion protective coating is at least 2,6 mm. |
