Metal Fillers & Putties

The primary advantage is chemical bonding. Unlike standard polyester fillers, an epoxy filler for metal creates a permanent chemical bond with the substrate. This results in superior strength, moisture resistance, and minimal shrinkage, making it the preferred choice for structural repairs where long term stability is required.

While many of our metal repair putty products are versatile, it is important to match the filler to the specific metal. For instance, using a standard steel based putty on an aluminum surface may lead to poor adhesion due to differences in thermal expansion and oxidation. Always choose an aluminum filler when working with non ferrous materials to ensure the repair lasts.

Yes, provided you choose the correct grade. Our heavy duty steel metal putty products are designed to cure to a very hard state, making them suitable for drilling, tapping, or filing. This is especially useful if you need to restore a stripped thread or rebuild a damaged flange on a mechanical component. Always check the technical data sheet for the specific cure time before attempting to machine the filler.
