Wet chemical coatings are applied to automobile glass and CRTs to provide new optical, electrical and chemical functions on their surface. Examples of the practically used functional wet chemical coatings are colored and water repellent coatings on glass for automobiles, and antireflective-antistatic and antireflective-electromagnetic wave shielding coatings on CRTs. Performance and composition of the various wet chemical coatings as well as the technology trends will be described in this report.
