Product Description
A 2-part hybrid polymer coating for the encapsulation of any shape, size or configuration of flanged joint or other equipment. Designed to exclude moisture and prevent crevice, galvanic and atmospheric corrosion, Belzona 3412 is a tough, isocyanate-free, flexible topcoat which does not require heat or specialist tools for application.
Can be simply applied by brush or spray to new or deteriorated equipment. When used in combination with the release agent/corrosion inhibitor Belzona 8411, the coating can be easily cut, peeled back and resealed to allow inspection of fastenings. Can also be used with the Belzona Spray Gun for fast and efficient application.

Frequently Asked Questions
One of the most common issues with flanges and fastenings is corrosion, which can lead to joint failure, leaks and costly downtime. This includes:
- Crevice corrosion — in narrow gaps between flange faces and bolts where moisture becomes trapped
- Galvanic corrosion — when dissimilar metals (e.g. stainless steel bolts and carbon steel flanges) contact in the presence of an electrolyte
- Atmospheric corrosion — from long-term exposure to humidity, salt spray and pollutants
Belzona 3412 encapsulates the entire flange assembly, preventing moisture ingress and isolating metal surfaces to significantly reduce corrosion risk.
