CL650 Hardener is a 2K polyurethane hardener formulated for use within the Challenger paint system. It ensures proper curing and crosslinking of Challenger 2K topcoats and clears, providing a durable, high-gloss finish with strong chemical and weather resistance.

Usage Instructions:
Mix CL650 Hardener at the recommended ratio with the corresponding Challenger 2K topcoat or clearcoat. Stir thoroughly before application. Apply 2–3 coats, allowing appropriate flash-off times between coats.

Ensure materials are at room temperature (18–25°C) before use. Do not return activated material to the original container. Close the can tightly after use to prevent reaction with moisture.

CL60 Hardener is suitable for use in professional refinishing environments and can be adapted for spot, panel, or overall applications depending on temperature and job size.
