AGC Asahi Glass's CYTOP amorphous fluoropolymer is a series of high-performance materials. Its model naming is not arbitrary but follows a clear set of rules to facilitate user selection based on specific needs. Model Naming Rules: Four-Dimensional Coding System CYTOP model names include key information such as molecular weight, functional group type, solvent, and temperature. Prefix (Molecular Weight): CTL: Low molecular weight (approximately 150,000-200,000), suitable for applications requiring thinner, more uniform coatings. CTX: Standard molecular weight (approximately 250,000-300,000), generally resulting in better coating mechanical strength. CT: Basic model identifier. Middle Number (Temperature/Properties) 809: High-temperature type, maximum operating temperature 180℃. 109: Medium-temperature type, maximum operating temperature 100℃. 107: Special modified type. Suffix Letter (Functional Groups and Solvents): Functional Group Type: A: Terminal -COOH (carboxyl group), strong adhesion to glass, metal, and other substrates. M: Ended with -CONH~Si(OR)n, exhibits good adhesion to silicon-containing substrates (such as silicon wafers). S: Ended with -CF3, does not participate in chemical bonding, suitable for specific functional layers. Solvent Type: E: Represents HFE (hydrofluoroether). K: Represents HFC (hydrofluorocarbon). (No suffix): Represents PFC (perfluorocarbon).

💎 Selection Guide When choosing a CYTOP model, consider the following: Based on process temperature: If the process temperature is >120°C, choose the 809 series; if the temperature is room temperature or below 100°C, the 109 series offers better value. Based on substrate type: Choose type A for glass/metal; type M for silicon/quartz; type S for specific functional layers.
Based on coating method: Spin Coating: Use a solvent with a boiling point of 180°C (e.g., CT-SOLV180). Dip Coating: Use a solvent with a boiling point of 100°C (e.g., CT-SOLV100E/K). Spray Coating: Two solvents can be mixed.
