Belzona Facts
Belzona 5811 was selected because of it's rating for hydrocarbons, adhesion and temperature rating. The bag house bearing wheel needs to have a service life of 8 years due to the cost of replacement. Without a protective coating these units required extensive service for corrosion and oxidation control.
