Belzona Polymerics Limited has pioneered a new generation of erosion resistant coatings formulated to prevent damage to spray equipment.

Superior erosion protection can now be achieved without damaging the spray equipment with Belzona’s new generation of spray applied filler-free polymer alloy that provides the robust protection of a ceramic coating without causing wear or damage to spray equipment.

Belzona is a world leader in the design and manufacture of polymer repair composites and industrial protective coatings.

Conventional ‘sprayable’ ceramic filled coatings not only cause extensive damage to equipment but also provide only a limited level of erosion/ corrosion protection. Belzona 1331 and Belzona 1381 coatings eliminate these issues while providing superior erosion resistance.

A robust and durable filler is typically used in fluid conveying equipment such as pipelines, pumps, valves and chutes to protect against erosive conditions. Ceramic fillers are unsuitable for spray application due to the hard, angular nature of the ceramic particles causing damage to equipment. 

The pioneering Belzona technology now helps achieve robust protection without causing damage to equipment.

The Belzona corrosion resistant coatings can be used in a wide range of abrasive environments where brush or roller application is not practical. The new coatings also provide resistance within high temperature immersion. Belzona 1331 was found to be suitable for immersion at temperatures up to 50°C while Belzona 1381 was suitable for immersion at temperatures up to 95°C.

The excellent edge retention and film build-up of the polymer alloy means the material can also be used in a variety of geometries, including girth welds on pipeline internal field joints. The recent application of Belzona 1331 on marine equipment demonstrates this versatility. 

Belzona’s Technical Services Engineer Kyle Flanagan explains that marine equipment, which was previously difficult to protect due to internal pitting, small diameter and aggressive service conditions is now enjoying successful service following the application of Belzona 1331 using spin spray techniques.

Superior erosion resistance, rapid application times and long-term corrosion protection are some of the benefits of Belzona 1331 and Belzona 1381 coatings.
