MetLQ^TM AL-1001 — Aluminium Casting Blowhole Repair & Filling Putty

Aluminium casting blowhole repair putty for porosity correction, pinhole sealing, cavity rebuilding and worn-surface restoration. MetLQ^TM AL-1001 forms a dense, rigid repair layer with strong adhesion to aluminium substrates used in casting and machining operations.

After full curing, the repaired area becomes hard and metal-like — allowing filing, grinding, drilling, tapping and machining to restore dimensional accuracy. Bond strength and shape remain stable under service heat and mechanical load, making it suitable for pre-coating and assembly preparation.

• Strong adhesion on aluminium and metallic substrates
• Effective blowhole, pinhole and porosity filling
• Rigid repair layer — machinable after full cure
• Resistant to oil, moisture, vibration and industrial atmosphere
• Temperature resistant up to 250°C

• Mix Part-A and Part-B in the specified ratio until uniform
• Stir until colour and texture are completely consistent
• Apply with firm pressure to ensure complete cavity fill
• Keep slightly above surface level for easier finishing

After curing, excess material can be removed by sanding, grinding or machining to achieve accurate surface alignment. Applying the compound slightly above the surface level improves finishing control. Ideal for machinable epoxy applications requiring precise dimensional restoration.
