乐泰冷块TM 3791是一种新型的紫外光固化“冷”阻挡粘合剂，使光学制造商能够使用各种脱粘剂和技术生产几乎无变形且容易脱粘的镜片表面。这种粘合剂是镜片阻挡工艺的重大进步，因为它消除了热诱导阻挡应变；这是当前热螺距阻挡方法遇到的最大问题。此外，这种封口工艺减少了昂贵的加工时间，与现有工具兼容，利用方便的即用包装，几乎消除了当前技术的环境问题(溶剂)。
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.
