Working Life - Will vary according to temperature. At 68°F (20°C) the usable life of mixed material is 1 hour 45 minutes.
Coverage Rate - The Belzona 5811 should be applied in 2 coats to achieve a minimum thickness of 16 mils (400 microns).
The theoretical coverage rate at 16 mils (400 microns) is 27ft2 (2.5m2)/liter. Refer to the Instructions for Use for practical coverage rate guidelines.Cure Time - Allow to solidify for the times shown in the Belzona IFU before subjecting it to the conditions indicated.

- Chemical Resistance
The material will demonstrate excellent resistance to a broad range of chemicals. For a more detailed description of chemical resistance properties, refer to relevant Chemical Resistance chart.
- Heat Resistance
Heat Resistance - For many typical applications the material is suitable for continuous immersion in aqueous solutions up to 122°F (50°C). Please consult Belzona TKL for additional advice where immersed applications will operate close to 122°F (50°C).
Dry Heat Resistance - The indicated degradation temperature in air based on Differential Scanning Calorimetry (DSC) operated in accordance with 1SO11357 is typically 320°F (160°C). For many applications, the product is suitable down to -40°F (-40°C).
- Immersion Resistance
Atlas Cell - When tested in accordance with NACE TM 0174 the coating will exhibit no rusting (ASTM D610 rating 10) or blistering (ASTM D714 rating 10) after 6 months immersion in de-ionized water at 104°F (40°C) or 4 months at 122°F (50°C).
Seawater Immersion - When tested in accordance with ISO 2812-2, no blistering, rusting, cracking or delamination was observed after 6 months immersion in seawater at 122°F (50°C).
Storage & Handling
- Shelf Life
Separate base and solidifier components shall have a shelf life of 5 years from date of manufacture when stored in their original unopened containers between 32°F (O°C) and 86°F (30°C).
