- Tell me about the method for improving adhesiveness when applying CYTOP® onto a plastic substrate.
- It is possible to improve the adhesiveness by using the CYTOP® primer “CT-P10”. However, because this primer contains toluene, it cannot be exported overseas from Japan. Please refer to the technical materials for more information.
- Tell me about the method for improving adhesiveness when applying CYTOP® onto glass, silicon or similar inorganic type substrate.
- It is possible to improve adhesiveness by using an amino-based silane coupling agent (example: “KBE-903” from Shin-Etsu Chemical Co., Ltd.) Please refer to the technical materials for more information.
- Tell me about the CYTOP® patterning method.
- CYTOP® can be patterned by doing dry etching using O2 gas. Please refer to the technical materials for more information.
- Tell me about CYTOP®'s stripping method.
- CYTOP® can be stripped with “oxygen etching”, “UV irradiation + ultrasonic immersion”, or “CYTOP® solvent”. Please refer to the technical materials for more information.
- Tell me about CYTOP® coating characteristics (molecular weight, density,and dry film thicknesses per spin rotation speed or pulling speed).
- We have data on the film thickness curve for spin coating and dip coating. Please refer to the technical materials for more information.
- What is CYTOP®'s solution viscosity per dilute solvent, molecular weight, and density?
- We have measured the solution viscosity per density. Please refer to the technical materials for more information.
- Tell me about CYTOP®'s curing conditions.
- The most suitable bake conditions vary depending on the film thickness, substrate, process, etc. Basically, after “air seasoning”, a “pre-bake” is performed for “degassing and solvent removal”, followed by a “final bake”. Please refer to the technical materials for more information.
- Tell me how to make CYTOP® S-type adhere to a substrate.
- The terminal functional group for “CYTOP® S-type” is “-CF3”, so it will not adhere to a substrate. However, by applying “CYTOP® A-type” in between the substrate and the S-type, it is possible to make the S-type adhere to the substrate. Please refer to the technical materials for more information.
- I would like a CYTOP® film (several mm thickness), so please tell me how to create it.
- It is possible to create a CYTOP® film by making a cast using CYTOP® S-type and a mold. Please refer to the technical materials for more information.
- What is CYTOP®’s infrared transmission ratio?
- We have measurement data up to 25μm wavelengths. Please refer to the technical materials for more information.
- Tell me about CYTOP®’s thermostability.
- CYTOP®’s thermal decomposition starting point is at 400°C, so we ask you to use it at 350°C or below under the condition of room temperature in an air atmosphere. Please refer to the technical materials for more information.
