ISOPON Metal Fix is a specialized, high-density metallic polyester filler designed specifically for high-strength repairs on metal substrates. Infused with aluminum particles, it provides a repair that mimics the thermal expansion and structural characteristics of metal, making it far superior to standard fillers for areas subjected to stress, heat, or vibration. Its silver-grey finish provides an excellent visual match for bare steel and aluminum.
Key Performance Features:
- Aluminum-Infused Strength: The addition of metallic flakes provides a tougher, more durable repair that is less brittle than conventional fillers.
- Superior Thermal Stability: Engineered to expand and contract at a rate similar to the metal substrate, significantly reducing the risk of "mapping" or cracking during temperature fluctuations.
- Corrosion Resistance: Offers an extra layer of protection for the metal underneath, helping to prevent moisture from reaching the substrate.
- High-Vertical Stability: Features a thick, creamy consistency that allows for high-build application on vertical surfaces without sagging or "slumping."
- Excellent Sandability: Despite its metallic content, it sands down easily to a fine, smooth finish that requires minimal finishing putty.
