Epoxy Filling & Fairing Compounds

Sika's epoxy filling and fairing compounds are two-component systems consisting of a resin and a hardener component. These systems provide superior adhesion and high strength, as well as outstanding moisture and chemical resistance. While these  filling and fairing systems are sandable several hours after application, they provide an exceptionally smoother surface with minimal pinholes. Suitable for a wide range of end-markets, their ability to be used above and below the waterline makes them an excellent choice for the marine industry for large fairing applications on aluminum, steel, fiberglass, and wooden boats.
