- Application Information
Working Life - Will vary according to the temperature. At 68°F (20°C), the usable life of the mixed material is 1 hour.
Coverage Rate - Applied at a thickness of 10 mils (250 microns) per coat, a theoretical coverage rate of 43 sq. ft (4 m?) / liter should be achieved. Refer to Belzona IFU for guidance with regard to practical coverage rates.
Cure Time - The cure time is dependent on ambient temperature. Allow to cure for the times shown in the Belzona IFU before subjecting it to the conditions indicated.

- 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 application 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 302 °F (150°C), For many applications, the product is suitable down to -40°F (-40°C).
Atlas Cell Cold Wall Immersion Test - Atlas Cell Immersion Resistance, when determined in accordance with NACE TMO174 procedure A, will result in no rusting (ASTM D610 rating 10) or blistering (ASTM D714 rating 10) after 6 months continuous immersion in tap water at 104°F (40°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 (0°C) and 86°F (30°C).
