Sea Hawk Hawk Epoxy Clear Finish Catalyst C5-S2, 2.33 Gallon, Clear

The Sea Hawk Hawk Epoxy Clear Finish Catalyst (part number C5-S2) is a liquid hardener formulated for use with Hawk Epoxy R1 Resin, producing a very clear finish over fiberglass cloth and coating applications with exceptional moisture barrier characteristics. It is designed for boat builders, restorers, and DIY applicators who need a coating system that stays optically clear rather than yellowing or clouding over time.

This catalyst is particularly suited to natural wood and carbon fiber clear coat applications, curing without blush so the finished surface does not require additional wiping or surface prep before topcoating. It offers longer working times in very warm temperatures, giving applicators more control when working in hot shop or marina conditions where standard catalysts can kick too quickly. The clear, resin-based liquid is compatible with carbon, fiberglass, and wood substrates, and this catalyst formulation may also be used under Sea Hawk marine wood varnish as part of a layered clear-coat system.

Supplied in a 2.33 gallon container, this catalyst is intended to be paired with its companion Hawk Epoxy R1 Resin at the manufacturer's specified mix ratio to achieve a proper cure. It ships as a single unit (package quantity of 1).
