A 2-part spray- or brush-applied epoxy coating for erosion and corrosion protection of equipment operating under continuous immersion up to 50°C (122°F). This solvent-free coating can be easily mixed and applied at ambient temperatures as a one or two coat system. Its 24 hours overcoating window allows large applications to be quickly completed, reducing downtime.

Due to its capability for high film build in a single coat without sagging and superior erosion resistance, Belzona 1331 is ideally suited to be used as an epoxy pipe lining for protection of girth welds on internal field joints. This new generation spray-applied filler-free coating provides the robust protection of a ceramic coating without causing wear or damage to spray equipment.

Key benefits:

Outstanding erosion and corrosion resistance under immersed conditions

Rapid application by airless spray without wear to spray equipment; can also be brush-applied where required

Allows for one or two coat application with 24 hours overcoat window

Capable of high-build application (> 1250 microns) in a single coat without sagging

Excellent cathodic disbondment resistance

Excellent flexibility, toughness and impact resistance

Outstanding chemical resistance against a wide range of chemicals

Available in light colours to aid visibility in dark vessels during application and inspection

Application and cure at room temperature - no hot work involved

Reduced health and safety risks as it is solvent-free

Excellent adhesion to most metal surfaces including carbon steel, stainless steel and specialist steels

Applications for Belzona 1331 include:

Erosion and corrosion resistant coating for process vessels, separators, pumps, heat exchangers and condensers operating under immersion

Epoxy pipe lining for protection of girth welds on internal field joints

Repair of worn and damaged chutes and hoppers

Long-term corrosion protection of scrubber units

Key technical data:

Working life at 25°C (77°F) 40 minutes

Time to immersion service at 20°C (68°F) 3 days

Pull off adhesion (D4541 / ISO 4624) 4900 psi (33.8 MPa) on grit blasted mild steel

Coverage rate Practical coverage rate for a 2 coat system:

2.1 sq.m. (22.6 sq.ft.) per kilogram per coat

Temperature resistance 50°C (122°F) immersed, 120°C (248°F) dry

Bonds to Carbon steel, stainless steel, specialist alloys and other metals and materials

Typical applications Spray or brush applied epoxy coating for erosion and corrosion protection of equipment under immersion
