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 F2 Structural Adhesive Filler thickens to an off-white color, creating a general purpose thickening additive for bonding, gap filling and filleting.
Mix to a workable consistency. Allows for sag free and easy flow properties for vertical and overhead applications.
F2 Filler is Sea Hawk's most versatile filller. It produces strong bonds and is the best Sea Hawk filler to use for bonding with fillets. Its fiber content makes it moderately difficult to sand.
In decreasing order of suitability, use F2 Structural Adhesive Filler for bonding with fillets, then for bonding hardware, general bonding, and laminating. F2 mixtures are typically too thick to use for fairing.
Heavy on the technical side...
F2 Structural Adhesive 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.
