MH101 is a hardener designed for use with compatible acrylic enamel automotive paints. It is used to activate the paint system before spraying, helping the coating cure properly and provide a more durable finish than uncatalyzed enamel.

This hardener is commonly used in automotive refinishing, repair work, restoration projects, and general paint jobs where acrylic enamel paint is being applied. When mixed correctly with the recommended enamel paint, MH101 helps improve hardness, chemical resistance, gloss retention, and overall film strength.
