“The simplest method for separating a lens bonded with Norland Optical Adhesive is to immerse the lens in a solvent combination made up of the following: methylene chloride, 100 parts by weight -methanol, 15 parts – concentrated ammonia (26 Baumé or 29% NH ), 2 parts. The methylene chloride is the active solvent and the other solvents increase its activity.The simplest method for separating a lens bonded with Norland Optical Adhesive is to immerse the lens in a solvent combination made up of the following: methylene chloride, 100 parts by weight -methanol, 15 parts – concentrated ammonia (26 Baumé or 29% NH ), 2 parts.
