Since most fluoropolymers are insoluble, they need to undergo a baking process to fix them onto the substrate. CYTOP can eliminate this process. Since it can be dissolved in a special fluorocarbon solvent, it is easy to coat it onto a substrate. CYTOP takes advantage of maintaining its high transparency. CYTOP has three types each with a different functional group at both ends of the polymer.
| Type | End functional group | Characteristics | Example of application |
|---|---|---|---|
| -COOH | • Metal and glass can be coated by using a silane coupling agent together with this type of CYTOP • Plastic can be coated by using a special primer together with this type of CYTOP • Transparent to visible light |
Anti-reflection film Optical membrane Protective layer Water and oil repellent Electric insulator |
|
| -CONHSi~(OR)n | • One-step coating of metals and glass can be done. | Protective layer Water and oil repellent Electric insulator |
|
| -CF3 | • High transparency for wide range of light from visible light to UV • Tough UV resistance • Non-adhesion |
Pellicle Optical materials Mold release material |
