ATOROZ ATZ‑MS25 – Mold Sealer
Product Description
The Exothermic Mould Sealer is a high‑performance sealing compound formulated specifically for graphite moulds used in exothermic welding. Its primary function is to prevent molten metal leakage, ensuring a clean, controlled, and safe welding reaction.
With excellent adhesion to graphite surfaces and resistance to extreme temperatures generated during exothermic reactions, the sealer maintains its integrity without burning, cracking, or contaminating the weld.
The 250 g pack size is ideal for field technicians, offering sufficient material for multiple welds while remaining compact and easy to carry.
- High‑temperature resistance — stable under exothermic reaction heat
- Leak‑proof sealing for graphite mould joints and cable entry points
- Improves weld quality by ensuring proper mould alignment
- Non‑flammable and non‑contaminating formulation
- Easy manual application with consistent pliability
- Compatible with all exothermic welding mould systems
- Extends mould lifespan by reducing thermal stress and leakage damage
