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 全文 »

最近又有网友咨询到DEVCON 14167结构胶产品，记得之前的文章有提到这款产品，参看《得复康DEVCON PUH94167 TDS》，之前也曾经尝试找过DEVCON 14167的官方技术资料，一直没有找到，只是在一些电子商务网站上有个别代理商贴出了部分技术参数。今天又抽空找了一下，果然在互联网上找到了官方的技术资料，贴在此处，大家共同学习之！  完整版PDF文件请到文章末尾下载。

Surface  Preparation:Clean surface by solvent-wiping any deposits of heavy grease, oil, dirt, or other contaminants. Surface can also be cleaned with industrial cleaning equipment such as vapor phase degreasers or hot aqueous baths. If working with metal, abrade or roughen the surface to significantly increase the microscopic bond area and optimize the bond strength.

Application  Instructions:

1. Apply mixed product directly to one surface in an even film or as a bead.

2. Assemble with mating part within recommended working time.

3. Apply firm pressure between mating parts to minimize any gap and ensure good contact (a small fillet of product should flow out the edges to display adequate gap fill).

4. Bond line thickness of mixed adhesive should be @ .030” for optimum adhesion.

For very large gaps:

1. Apply product to both surfaces.

2. Spread to cover entire area OR make a bead pattern to allow flow throughout the joint. Let bonded assemblies stand for recommended functional cure time prior to handling.

ADDITIONAL PRODUCT INFORMATION:

– Can withstand processing forces

– Do not drop, shock load, or heavily load

– Intermittent exposure to temperatures above 250°F do not reduce performance characteristics

STAINLESS STEEL AND ALUMINUM APPLICATIONS:

Apply Devcon Metal Prep 90 to prime and condition aluminum and stainless steel surfaces prior to using Compossite Welder FS. Metal Prep 90 is fast-drying at ambient temperatures. Composite Welder FS can be applied within minutes of its use. Overlap shear strength will improve 30-40% if Metal Prep 90 is used.

 Storage:Store between 55°F and 75°F.  Continuous storage above 75°F reduces the shelf life of the materials. Prolonged exposure above 100°F quickly diminishes the product’s reactivity, and should be avoided. Shelf life can be extended by refrigeration between 45°F and 55°F. DO NOT FREEZE.

Compliances:Meets UL 746C Polymeric Adhesive Systems, Electrical Equipment-Component

Chemical Resistance:  Chemical resistance is calculated with a 7 day, room temp. cure (30 days immersion) @ 75°F)

Precautions:
Please refer to the appropriate material safety data sheet (MSDS) prior to using this product.
