Belzona Facts
Belzona has successfully proven to be a high cost-effective solution that has saved the Refinery $168,000 and provided longer longevity than the conventional solvent coating. A 4-year inspection found the majority of the original coating in a perfect condition, still glossy and tightly adherent. During a 7-year inspection, the coating is virtually unchanged from the 4-year inspection with both black and beige coats still present at full thickness. After a 9-year inspection, the application is still perfect and operating.
