Solvent pop is caused by what scenario?

Solvent pop is caused by what scenario?

• A. Excessive air flow
• B. Low ambient temperature
• C. Trapped solvent from improper flash time
• D. Over mixing the paint

Answer: (C)

Solvent pop happens when solvent remains trapped in the film because there wasn’t enough flash-off time between coats. As the coating cures, the trapped solvent tries to escape and forms tiny bubbles that pop, leaving a cratered or blistered finish. So the scenario that best explains solvent pop is trapped solvent caused by improper flash time. Other factors like air flow, low temperature, or over-mixing can affect the finish in other ways, but they don’t create the same trapped-solvent condition responsible for solvent pop.
