Metal repair material for application to

1161
wet and oil-contaminated surfaces

Belzona 1161 is a two-component, surface-tolerant,

paste grade system for repairing and rebuilding
machinery and equipment.

This fully machinable, surface-tolerant product

displaces fluid from the substrate and therefore can
be applied to wet and oily surfaces as well as for
underwater application.

This material does not shrink, expand or distort during

cure and can be applied in thick or thin sections in
one operation. It is easy to mix and apply without the
need for specialist tools and can be machined using
conventional tools.
