Sea Hawk Hawk Epoxy Ultra Slow Catalyst, 1.66 Pint, C1-S1

The Sea Hawk Hawk Epoxy Ultra Slow Catalyst (C1-S1) is the hardener component used together with Hawk Epoxy R1 Resin for marine construction and repair work. It is formulated as an ultra slow cure catalyst, giving applicators an extended working time that is especially useful in higher ambient temperatures where faster-curing epoxies can set up before the job is finished. Once combined with R1 Resin, the resulting epoxy system delivers superior adhesion and strength, along with reliable bonding, filling, and moisture barrier performance.

This catalyst comes in paste form and is packaged in a 1.66 pint container, sized to pair with the corresponding volume of R1 Resin for a proper mix ratio. It is compatible with wood substrates, making it well suited to woodworking and repair applications on boats and other wood structures. Do not use this catalyst under Sea Hawk marine wood varnish.

Frequently Asked Questions

What is the Sea Hawk C1-S1 catalyst used for? C1-S1 is an ultra slow cure catalyst designed to be mixed with Hawk Epoxy R1 Resin for marine construction and repair work, providing superior adhesion, bonding, filling, and moisture barrier qualities.

What resin does C1-S1 pair with? C1-S1 is designed for use with Hawk Epoxy R1 Resin; the two components are combined together to form the working epoxy system.

Why choose the Ultra Slow version instead of a faster catalyst? The Ultra Slow cure speed of C1-S1 gives an extended working time, which is particularly useful at higher temperatures where a standard catalyst might begin curing before an application is complete.

How much catalyst is in this container? This Sea Hawk C1-S1 catalyst is packaged in a 1.66 pint container.

What form does the catalyst come in? C1-S1 is supplied as a paste, not a liquid, so it can be measured and mixed with R1 Resin by volume or weight ratio.

Can this catalyst be used on wood? Yes, C1-S1 is compatible with wood substrates and is commonly used for woodworking and wood repair applications.

Is there anything C1-S1 should not be used with? C1-S1 should not be used underneath Sea Hawk marine wood varnish.

How much does the C1-S1 catalyst weigh? The 1.66 pint container of Sea Hawk C1-S1 catalyst weighs 0.88 pounds.

What kind of adhesion and strength can I expect from this epoxy system? When mixed with Hawk Epoxy R1 Resin, C1-S1 catalyst produces a system with superior adhesion and strength, particularly at higher temperatures.

Is C1-S1 sold as a standalone product or does it require another component? C1-S1 is the catalyst (hardener) half of a two-part epoxy system; it must be combined with Hawk Epoxy R1 Resin to cure into a usable epoxy.

How many units come in one package of C1-S1? Each package of Sea Hawk C1-S1 catalyst contains a package quantity of 1.
