Fillers and Additives
Fillers and additives are used alongside epoxy resins to tailor the material’s properties for specific tasks, allowing you to get the right balance of strength, weight, and workability.
By combining epoxy with different fillers, you can create mixtures suited to bonding, filleting, fairing, or gap filling—ranging from high-strength structural blends to lightweight, easily sanded compounds for surface finishing. Additives can also be used to adjust handling characteristics such as flow and consistency.
Used correctly, fillers and additives greatly expand the versatility of epoxy systems, making them an essential part of any well-rounded workshop or boatbuilding setup.
The products in this category are selected to work seamlessly with the resin systems available in the store, helping you achieve precise, reliable results across a wide range of applications.
