F5 Light Density Fairing Filler - 4 oz

Any of the six Hawk Epoxy Fillers can be used with any combination of Hawk Epoxy Resin and Catalysts, giving the user a large range of epoxy blends, all within a single system.

The F5 Light Density Fairing Filler thickens to a reddish brown color. The F5 filler produces an easy to sand and carve fairing compound while still remaining strong and light weight.

The F5 Filler is one of Sea Hawk's more versatile light weight fillers.
In decreasing order of suitability, F5 Light Density Fairing Filler works well for bonding with fillets, and can also be used for laminating. The F2 and F3 fillers, respectively, work better for these tasks, but at the expense of more difficult sanding. Easy to sand, the F5 filler (along with the F6 MicroSphere Filler) is suitable for fairing.


Heavy on the technical side...

F5 Light Density Fairing Filler is part of the Hawk Epoxy System.
The foundation of the Hawk Epoxy System is R1 Epoxy Resin which can meet a multitude of application requirements using your choice of eleven different catalyst and fairing options.
Bonding, fairing, coating, waterproofing, and air exchange reduction have never been easier. Simply choose a catalyst for your working conditions, then select an optional filler to fine-tune the mixture's strength and thickness for bonding, filleting, laminating, or fairing ability.

When using fillers, blend in small amounts to the mixed resin and catalyst until the desired thickness is achieved.
Depending on the use, mixing in more or less of the filler material will allow multiple uses with the same filler. For example: • For laminating flat panels or bonding large surfaces, filler should be mixed to a pourable or injectable consistency. • For general bonding, filleting or bonding hardware, mix material to a slightly to moderately thick consistency. • If you desire a zero-sag effect, mix to a very thick consistency. This can act as a filler for uneven surfaces without worry of sag. • To ensure maximum adhesion and strength, use only enough filler to avoid sagging or running. When using a resin/catalyst/filler mixture for bonding, a small amount of mixture should squeeze out from between the two items that are being bonded to each other when they are pushed together. Increasing the filler to resin/catalyst ratio will deduct strength and increase sandability.
