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.
