Major Types of CYTOP™

• Dip Coating: CTL-109AE
• Spin Coating: CTX-809A; CTX-809AP2; CTL-809M

How to use CYTOP™

1. AGC normally supplies a 9% solution.
2. To achieve the thickness desired, control the concentration of the CYTOP™ solution as well as speed of coating. For this purpose, we supply the solvent at the same time as the CYTOP™ solution.
