Erosion-corrosion damage to equipment operating in contact with water and other aqueous solutions at high temperatures is a major problem faced by design and maintenance engineers.
While protective coatings can be successfully used at moderate temperatures, migration through the coating readily occurs at temperatures above 90°C (194°F) . This gives rise to blistering and premature breakdown.
Conversely, barrier coatings such as glass flake systems offer improved migration properties but are limited by poor cavitation and abrasion resistance, susceptibility to impact damage, and difficulties in application.
By combining a unique blend of inorganic erosion-corrosion resistant reinforcing agents with a radically new, densely crosslinked heat resistant polymer, a revolution in high temperature coating technology has been created. Belzona® 1391 makes protection against erosion-corrosion in high temperature environments a reality.
