Belzona 3412

Encapsulating membrane for flanges, fittings and connectors

Flexible and peelable system, used for encapsulating flanges and bolt fastenings to protect against moisture ingress and prevent corrosi

Belzona 3412 is a flexible encapsulating membrane, which protects various joints and equipment from moisture ingress, dust and the environment.

It can be applied by brush or spray gun (including the Belzona Spray Gun) to new or corroded assets, eliminating corrosion. Fibres in its formulation enhance Belzona 3412’s durability, whilst the in-built corrosion inhibitor ensures long-term protection.

When used in conjunction with Belzona 8411, a release agent/corrosion inhibitor, Belzona 3412 can be cut and peeled for inspection during maintenance, then resealed for continued protection.
