Belzona 1251 (HA-Metal)
A durable, single component metal repair composite based on a silicon alloy blended with a heat activated epoxy resin. Designed to repair and protect metal surfaces suffering from Corrosion under Insulation (CUI), Belzona 1251 (HA-Metal) can be easily applied by spatula, applicator or brush.
This heat activated material can be applied directly onto hot surfaces (70-150°C / 158-302°F) with minimal surface preparation avoiding production downtime. Once cured, this solvent-free repair composite provides outstanding corrosion protection.
Belzona 1251 (HA-Metal) is ideally suited to be over coated with Belzona 5851 (HA-Barrier) to ensure long-lasting performance.
