配方類(lèi)型： CERAMICS AND GLASS
配方說(shuō)明： Coating for Optical Lenses (Colored Solution for Temporary
Identification of Lenses)
配方組成： Ethanol/Water/q.s.
Alcohol/Water-soluble Dye/0.25-0.5
"Alipal" CO-436/0.1
PVP K-30/2.0
配制方法： This coating solution should be kept below pH 10 as higher values may cause some insolubilization of the film after storage. PVP also has been insolubilized by certain azo compounds under exposure to light; therefore, it is suggested that azo-type dyestuffs be avoided. the coating may be removed easily from the glass with a slightly alkaline spray, before further processing of the lenses.
