Overview of Belzona 1812
A two-component system for repairing and protecting surfaces against abrasive attack. The product is based on high molecular-weight polymers and oligomers incorporating abrasion resistant ceramic aggregates. Belzona 1812 may be applied from 1/8 inch (3 mm) to unlimited thickness onto horizontal or vertical surfaces - half the minimum thickness of Belzona 1811.

Frequently Asked Questions
What is Belzona 1812 (Ceramic Carbide FP) used for?
Belzona 1812 (Ceramic Carbide FP) is a 2-part ceramic-filled epoxy paste for repairing and protecting metal surfaces against abrasive wear, applicable from 1/8 inch (3 mm) thickness — half the minimum thickness of Belzona 1811. It is used on pipe bends, wear plates, chutes, mixing bowls, and centrifuges.
How does Belzona 1812 differ from Belzona 1811?
Belzona 1812 can be applied at half the minimum thickness of Belzona 1811 (1/8 inch / 3 mm vs 1/4 inch / 6 mm) and supports a higher dry service temperature up to 212°F (100°C). It is preferred where thinner protective coats or higher service temperatures are required.
What service temperatures does Belzona 1812 support?
Belzona 1812 supports dry service up to 212°F (100°C) and wet/slurry service up to 176°F (80°C). The lower service temperature limit is -40°F (-40°C), making it suitable for a wide range of operating environments.
