Lenses typically separate after soaking in acetone for 10 to 60 minutes.
Debonding time is a function of surface area. Plano surfaces will require
more time than surfaces with only slight edge contact, therefore annular ring
designs of the mounting block are most efficient. Relief grooves or slots
in the metal block may also be used for promoting the deblocking process by
allowing the solution to come in contact with more of the adhesive.
may also be debonded just by heating between 80 and 100° C. After separation,
the components and tools are cleaned in the detergent/water solution.
life of the liquid is at least 6 months at room temperature if stored in the
original container away from UV light. Prolonged skin contact should be avoided
and affected areas should be washed with soap and water. Avoid prolonged vapor
inhalation and use in a well ventilated area.
