Sea Hawk C3-S1 Fast Cure Catalyst for Hawk Epoxy R1 Resin, 1.4 Pint

The Sea Hawk C3-S1 Fast Cure Catalyst is a hardener formulated for use with Hawk Epoxy R1 Resin, giving boat owners and builders a fast-curing option for construction and repair work. Paired with R1 Resin, this catalyst delivers strong adhesion, structural strength, and reliable filling and bonding performance, along with a moisture barrier quality that holds up even at cooler temperatures. Because it is a fast-cure formula, it is well suited to jobs where reduced working time or quicker turnaround matters, such as small repairs or projects done in cooler shop conditions.

This is a liquid, water-resistant, low-viscosity catalyst supplied in a 1.4 pint container, making it easy to measure and mix with the corresponding R1 Resin in small-batch repair and construction applications. It is compatible with wood substrates and is commonly used across general construction, repair, and woodworking tasks. Note that this catalyst is not intended for use under Sea Hawk marine wood varnish.
