Catalyst amount controls how fast the coating cures. When too much activator or hardener is added, the chemical reaction happens too quickly. This rapid cure prevents the film from flowing and leveling properly, and it can generate excess heat in the film. The result is an over-catalyzed condition, with problems like defects from rushing the cure, reduced pot life, and potential issues with adhesion or film integrity. If not enough catalyst is used, the cure would be slow (under-catalyzed), leading to a soft or tacky film. A properly catalyzed mix cures at the intended rate, giving good flow, leveling, and final film properties.
