Belzona 8411



Carbon Steel


Application Method:

The application was carried out in accordance with Belzona Know-How System Leaflet GSS-11.


Belzona Facts:

The customer chose Belzona since a competitor's solution required spray application by a special application team, leading to long shutdowns and increased costs. The customer chose Belzona 3411 as the system is quick and simple to use and can be easily peeled away, allowing easy access to flange fastenings. The system can also be easily resealed by their own maintenance personnel on site, keeping additional costs down. Belzona 3411 also provides excellent corrosion, UV and weather resistance.
