When mixed and applied as detailed in the Belzona Instructions for Use (IFU), the material is ideally suited to the following applications where a pourable or brushable grade of elastomer is advantageous:
- Multi-purpose rubber repair
- Horizontal expansion joints
- Casting flexible molds
- Diaphragms
- Casting gaskets
- Protecting exposed threads
- Application Information
Working Life - The usable life will vary according to temperature. At 68°F (20°C) use all mixed material within 15 minutes.
Application Method - Plastic applicator or stiff bristle brush.
Application Temperature - 41°F-104°F (5°C-40°C).
Overcoat - Will vary according to ambient temperature and humidity. See Belzona IFU for details.
Cure Time - Cure times will be reduced for thicker sections and extended for thinner applications. At a thickness of approximately 0.10 in. (0.25cm), allow to solidify for the times shown in the Belzona IFU before subjecting it to the conditions indicated.
Volume Capacity
The volume capacity is:
53.8 cu.in (881cm3)/kg
40.3 cu.in (661cm3)/750g unitCoverage Rate - At 15 mils (375 microns) thickness, each 750g unit will cover 18.9sq.ft. (1.76m2).
