Loctite Cold BlocTM 3791, a new uv-curing 'cold' blocking adhesive enables optical manufacturers to produce lens surfaces that are practically distortion free and easily debonded using a variety of debonding agents and techniques. 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 blocking methods. In addition, this blocking process reduces costly processing time, is compatible with existing tooling, utilizes convenient ready-to-use packaging and virtually eliminates the environmental concerns (solvents) of the current technique.
