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.

Key benefits:

In-situ application to live equipment operating at high temperature with minimal surface preparation

Multi-purpose durable metal repair composite

Single pack system, no weighing or mixing required

Reduced health and safety risks as it is solvent-free

Fast cure allowing equipment to be re-insulated with minimum delay

Excellent corrosion protection

Impact and abrasion resistance

Good chemical resistance against a wide range of chemicals

Excellent adhesion to metals including stainless steel, carbon steel, aluminium, brass and copper

Does not corrode
