Moisture-proof and insulation protection for electronic substrates: "Fluorinated conformal coating agent"
AegisCoat WOP-025
Improvement of electronic circuit board reliability: Contributes to the reduction of CO2 emissions as the thermal drying process is unnecessary! A coating agent that is resistant to temperature changes and has excellent long-term durability.
We have developed a "Fluorinated Conformal Coating" that provides "moisture-proof and insulation protection" for electronic substrates, leveraging our long-standing expertise in fluoropolymer polymerization technology and insights from the conformal coating market. Conventional organic solvent-based coatings require a thermal drying and curing process after application due to their boiling points ranging from 100°C to 130°C. Our "Fluorinated Conformal Coating" utilizes low-boiling fluorinated solvents, allowing for room temperature drying, thereby eliminating the need for thermal drying processes and significantly contributing to the reduction of fossil fuel usage and carbon dioxide emissions. Additionally, it is more resistant to temperature changes and offers superior long-term durability compared to traditional coatings for automotive applications, meeting international standards (IPC-CC-830). To accommodate users' specific requests, such as reducing drying time and controlling coating thickness, we also offer a range of products with varying concentrations. 【Features】 ■ No thermal curing process required ■ Contributes to the reduction of fossil fuels and carbon dioxide ■ Long-term durability ■ Compliance with various regulations ■ Exempt from fire safety regulations ★ For more details, please download the materials or feel free to contact us with any questions.
