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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003cp\u003eSupplied 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).\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sea Hawk\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e C5-S2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Form:\u003c\/strong\u003e Liquid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Clear\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Resin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Material:\u003c\/strong\u003e Carbon, Fiberglass, Wood\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVolume:\u003c\/strong\u003e 2.33 gallons\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 3.16 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 811577014839\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat resin does the Sea Hawk C5-S2 catalyst pair with?\u003c\/strong\u003e The C5-S2 catalyst is designed for use with Hawk Epoxy R1 Resin to produce a very clear fiberglass cloth and coating finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this catalyst yellow or cloud over time?\u003c\/strong\u003e No. The Sea Hawk C5-S2 clear finish catalyst is formulated for exceptional clarity and is intended to maintain a very clear appearance on fiberglass cloth and coating applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this catalyst suitable for wood and carbon fiber projects?\u003c\/strong\u003e Yes, the C5-S2 catalyst is designed for natural wood and carbon fiber clear coat applications, including use under Sea Hawk marine wood varnish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the cured finish need to be wiped down for blush before recoating?\u003c\/strong\u003e No wiping for blush is needed.
