    While fluoropolymer coatings are effective in reducing the pre-cooling time, quenching experiments have revealed that the formation of cracks in the coating during cooling enables a significant reduction in the pre-cooling time. The cracks affected the boiling heat transfer characteristics and accelerated the transition from film boiling to transition boiling during cooling. The high heat fluxes of subsequent transition and nucleate boiling contributed to the shorter pre-cooling time. The room temperature curable fluoropolymer coating is expected to have a wide range of applications because the coating is easy to apply and can be applied to narrow or curved surfaces such as the inside of pipes and tanks.
