Belzona 1311

Belzona 1311 is a repair composite designed for rebuilding and protecting metal against the effects of erosion and corrosion.

This cold-applied material benefits from excellent erosion resistance and can be used to restore equipment operating under immersion without the need for hot work.

Belzona 1311 demonstrates outstanding adhesion to a variety of substrates, allowing it to also be used as a high strenght structural adhesive for metal bonding. For long-lasting performance, it can be overcoated with another of Belzona’s 1311 Series materials.

Usage Areas: propeller, rudder, bow thruster, pump casings, impellers, seachests, HT coolers and covers, seawater pipeworks, flanges, sterntube outer Shell.
