Fast Curing, Surface Tolerant, Abrasion Resistant System for Patch Repairs

Belzona 1818 - Fast Curing, Surface Tolerant, Abrasion Resistant System for Patch Repairs.


Belzona 1818 is a fast curing, surface tolerant, abrasion resistant system ideal for patch repairs on surfaces subject to high erosion and abrasive environments.

Its fast curing properties results in minimal downtime for damaged equipment, and the product can experience full mechanical loading in as little as two hours after application.

This material has built in surface tolerant technology, enabling it to bond tenaciously onto steel substrates even when surface preparation is minimal or if the substrate is heavily contaminated with oil or water. The product can even be applied and cured underwater.

Supplied as a two-part system, Belzona 1818 is easy to mix and apply without the need for specialist tools and can be applied direct to the substrate with no need for an additional primer.


Key Benefits:
