Pitch and Wax Removal for Optics

  • Pitch & Wax Removal for Optics
Click image to enlarge
NuGenTec FluoSolv® formulated solvents have been used in many applications in the optics industry such as precision cleaning, deposition of anti-reflective & anti-static coatings and de-blocking. Many different types of pitch and wax are used for blocking during grinding and polishing of glass to make spherical and plano-optical components. FluoSolv CX® is a safe drop-in replacement for Asahiklin AK-225 solvent (Class II ODC) as well as nPB and other similar solvents. 

FluoSolv® CX has shown excellent solvency when used in a vapor-degreaser for removal of pitch (e.g. Trinidad, Gugolz) and wax (e.g. Fixturewax, Hypo Wax etc.) due to its Kb value being high (95-100).

Higher soil loading allows the solvent bath to last longer before replacement, resulting in cost savings for new solvent and lower production downtime.
Field data for various waxes and pitch type is shown below for FluoSolv® CX.
