Sea Hawk Hawk Epoxy Ultra Slow Catalyst, Size 2.33 Gallon - C1-S2

This is the Ultra Slow Catalyst for Sea Hawk's Hawk Epoxy R1 Resin system, packaged in a 2.33 gallon liquid container under part number C1-S2. It is formulated to pair specifically with Hawk Epoxy R1 Resin for construction and repair work, delivering superior adhesion, strength, bonding, and filling performance along with a reliable moisture barrier. The "Ultra Slow" formulation extends open/working time and is intended for use at higher temperatures, where a faster-curing catalyst would set up before the job is finished, giving fiberglass and wood repair work more time to be mixed, applied, and worked into place. As a liquid resin-based hardener, it is compatible with wood substrates and is used as part of a two-part epoxy system rather than as a standalone adhesive. One important compatibility note: this catalyst is not intended for use under Sea Hawk marine wood varnish, so it should be reserved for structural resin work rather than varnish topcoat systems. Boat builders, repair shops, and DIY owners working on fiberglass or wood repairs in warm shop or marina conditions benefit from the added cure time this catalyst provides compared to faster-setting options.

How much catalyst comes in one C1-S2 container? Each container holds 2.33 gallons of liquid catalyst.

Why choose the ultra slow version over a faster catalyst? The ultra slow formulation extends working time, which is especially useful at higher temperatures where a faster catalyst would begin curing before the repair or lay-up work is complete.

Can this catalyst be used under Sea Hawk marine wood varnish? No. Sea Hawk specifically states that the C1-S2 Ultra Slow Catalyst should not be used underneath Sea Hawk marine wood varnish.

What kind of adhesion and durability can I expect from this catalyst system? When combined with Hawk Epoxy R1 Resin, the C1-S2 catalyst produces superior adhesion, strength, bonding, and filling qualities, along with a moisture barrier for repair work.

Is this catalyst suitable for wood repairs? Yes, the C1-S2 catalyst is compatible with wood as well as general fiberglass construction and repair applications.

What form does the C1-S2 catalyst come in? It is a liquid catalyst, sold by volume in a 2.33 gallon container.

How much does a container of C1-S2 catalyst weigh? A container of the Sea Hawk C1-S2 Ultra Slow Catalyst weighs 3.21 pounds.

Does the C1-S2 catalyst work as a standalone adhesive? No, it is a catalyst intended to be mixed with Hawk Epoxy R1 Resin as part of a two-part epoxy system, not used on its own.

Is high heat a good environment to use this catalyst in? Yes, the ultra slow cure profile of the C1-S2 catalyst is intended for use at higher temperatures, giving extra working time before the epoxy sets.
