MH277 is a medium speed hardener used with compatible OMNI automotive clearcoat systems. It is designed to activate the clearcoat before spraying, helping the material cure properly and develop a durable, glossy finish.

Always follow the current product data sheet for the correct mixing ratio, temperature range, pot life, flash times, dry times, spray gun setup, and safety requirements. Proper hardener selection is important because temperature, job size, airflow, and application conditions can affect how the clearcoat sprays, flows, and cures.
