LOCTITE HF8075LV TDS 技术资料

最近乐泰官网的TDS查询网址进不去了，不知道是因为斯巴达的原因还是别的什么的原因。至少11月份开始像google的很多服务已经无法正常使用了。今天还收到了一个体制内朋友转发的斯巴达最终结果名单（如果属实的话估计接下来这几年又是保守派为主了）。一下子扯远了，还是谈回这份LOCTITE  HF8075LV的TDS技术资料，这款产品据说是乐泰为苹果定制开发的，至于用途点大家可以参看DEVCON的14167产品。  摘录TDS资料如下，需要查看PDF版本的朋友请到文章末下载：

Application	Bonding

LOCTITE® HF8075LV™ is a toughened, two component, room temperature curing methacrylate adhesive system. It is designed to comply with the low halogen content requirements for structural bonding of electronic assemblies. LOCTITE® HF8075LV™  cures  rapidly,  forming  tough,  resilient  bonds. Once statically mixed, the two component acrylic cures at room temperature. Cure times can be reduced with the addition of mild heat to the bonded assemblies. Typical applications include structural bonding of plastic and metal components that must withstand vibrations and impacts such as display, top case, structural frame to enclosure, and similar applications in the portable devices market.
