Overview of Belzona 1161
A 2-part composite material for metal repair and resurfacing based on a 100% solids, surface-tolerant epoxy resin reinforced with silicon steel alloy. This composite material is specifically designed for application to wet and oil contaminated surfaces, as well as for underwater applications. It is easy to mix and apply without the need of specialist tools and can be machined using conventional tools.
Key Benefits
Easy to mix and apply without specialist tools
Cures at room temperature without hot work
Outstanding resistance to a wide range of chemicals
Excellent dielectric and insulation characteristics
Machinable using conventional tools after cure
Bonds and cures underwater, including wet and oily surfaces
