Product Description

A 100% solids, single-component epoxy coating, which cures in contact with hot surfaces and is designed to prevent or protect metal from corrosion under insulation (CUI). Belzona 5851 (HA-Barrier) can be easily applied by brush and does not require any weighing or mixing.

This heat-activated material can be applied directly onto hot surfaces (70–150°C / 158–302°F) with minimal surface preparation, avoiding production downtime. Also available is Belzona 1251 (HA-Barrier), a heat-activated epoxy repair composite for filling pitting and bonding equipment.
