Sea Hawk F3-S Light Density Epoxy Microfiber Filler, 6 oz

The Sea Hawk F3-S is a light density adhesive microfiber filler designed to thicken epoxy resin into a workable, off-white paste. It is formulated for bonding a wide range of substrates, with particular strength in wood applications, making it a go-to choice for boat builders and repair work where wood surfaces need a reliable epoxy bond. Once mixed into epoxy resin, the F3-S microfiber filler creates a multipurpose adhesive that offers excellent wetting and penetrating characteristics, allowing the mixture to soak into porous surfaces before curing for a stronger mechanical bond.

Beyond general bonding, the F3-S filler is well suited to laminating work, where its fiber structure adds reinforcement between layers. Adding this filler to epoxy also increases impact and abrasion resistance compared to unfilled resin, which helps in areas subject to wear, flexing, or occasional knocks. The paste consistency makes it easy to control thickness and texture during application, whether filling gaps, building fillets, or creating a laminating paste. Each unit contains 6 fluid ounces of the microfiber filler material.
