Abstract

Loctite "Cold Bloc™", a new uv-curing blocking adhesive enables optical manufacturers to produce lens surfaces that are practically distortion free and easily debonded using a variety of eco-friendly debonding agents which eliminates the environmental concerns (solvents) of the current technique. The adhesive is a significant advance in the lens blocking process, as it eliminates heat induced blocking strain; the most significant problem encountered with current hot pitch or wax blocking methods. In addition, this blocking process reduces costly processing time, utilizes convenient ready-to-use packaging and is compatible with both conventional optical manufacturing processes and is applicable to those manufacturers using the Opticam line of equipment.
