It produces a rigid, high-strength, moisture-resistant bond and is the right choice when working temperatures are cool or when a quick return-to-service time is the priority. With a pot life of 9–12 minutes at 22°C (72°F), it suits smaller pours, laminating passes, and repair work where you want to move through multiple steps in a single session.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFast cure formulation — pot life of 9–12 minutes at 22°C (72°F)\u003c\/li\u003e\n\u003cli\u003eMix ratio: 5 parts 105 Resin to 1 part C205 Hardener by volume\u003c\/li\u003e\n\u003cli\u003eProduces a rigid, high-strength, moisture-resistant cured solid\u003c\/li\u003e\n\u003cli\u003eWell-suited to cool working conditions where slower hardeners may under-cure\u003c\/li\u003e\n\u003cli\u003e208 ml (7 oz.) bottle — sized for repair work and smaller laminating jobs\u003c\/li\u003e\n\u003cli\u003eCompatible with the West System 300 Mini Pump for accurate metered dispensing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eBest Use Case:\u003c\/strong\u003e The C205 Fast Hardener is the standard recommendation for customers doing fibreglass repairs, bonding, and laminating in cooler shop or outdoor conditions — typically below 21°C (70°F) — where a slow hardener would extend cure time impractically. The short pot life makes it less suitable for large pours or complex layups where extended working time is needed; for those applications, steer customers toward the \u003ca href=\"\/products\/11131376402468\"\u003eWest System 206 Slow Hardener\u003c\/a\u003e, the \u003ca href=\"\/products\/11131377483812\"\u003eC209SA Extra Slow Hardener\u003c\/a\u003e, or the \u003ca href=\"\/products\/11131377549348\"\u003eC209SB Extra Slow Hardener\u003c\/a\u003e.
