5 High-performance adhesives for demanding electronics applications. With the ever-increasing sophistication of electronics, you need the most dependable and versatile methods for their fabrication and assembly. 3M TM Scotch-Weld TM epoxies and Jet-melt TM adhesives have the performance characteristics that provide reliable bonds and seals for a broad spectrum of applications. From hard disk drive and printed circuit board fabrication to cellular phone and computer assembly, our adhesives can provide solutions that help improve product performance while streamlining assembly processes and reducing material costs. Electronic Grade () Epoxies For assembly of sophisticated electronics where outgassing and corrosion of material bonds are a concern, our two-part Electronic Grade () epoxies are an excellent alternative to mechanical fasteners and lower-grade adhesives. 3M Scotch- Weld epoxies produce far lower contamination levels of ionic and outgassing impurities than typical epoxy adhesives. This makes 3M Scotch-Weld epoxies ideal for the fabrication and assembly of critical components. One-Part Epoxies 3M Scotch-Weld one-part epoxies provide superior structural adhesive performance where durability, environmental resistance and chemical resistance are essential. One-part epoxies also eliminate mixing, weighing and work life limitations. What s more, they cure on demand when heat is applied, thereby offering flexibility in processing. Two-Part Epoxies If structural performance is a priority, consider the many solutions provided by 3M Scotch-Weld two-part epoxies. They re available in a wide range of formulations, performance profiles and handling characteristics. Precision dispensing is made easy with the 3M EPX Applicator System. Duo-Pak cartridges also offer room temperature storage and long shelf life for added convenience in many fabrication and assembly operations.

PRODUCT USE: All statements, technical information and recommendations contained in this document are based upon tests or experience that 3M believes are reliable. However, many factors beyond 3M s control can affect the use and performance of a 3M product in a particular application, including the conditions under which the product is used and the time and environmental conditions in which the product is expected to perform. Since these factors are uniquely within the user s knowledge and control, it is essential that the user evaluate the 3M product to determine whether is is fit for a particular purpose and suitable for the user s method of application. WARRANTY AND LIMITED REMEDY: Unless stated otherwise in 3M s product literature, packaging inserts or product packaging for individual products, 3M warrants that each 3M product meets the applicable specification at the time 3M ships the product. Individual productions may have additional or different warranties as stated on product literature, package insets or product packages. 3M MAKES NO OTHER WARRANTIES EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO ANY IMPLIED WARRANTY OF MERCHANTABLITY OR FITNESS FOR A PARTICULAR PURPOSE OR ANY IMPLIED WARRANTY ARISING G OUT OF A COURSE OF DEALING, CUSTOM OF USAGE OF TRADE. User is responsible for determining whether the 3M product is fit for a particular purpose and suitable for user s application. If the 3M product is defective within the warranty period, your exclusive remedy ad 3M s and seller s sole obligation will be, at 3M s option, to replace the product or refund the purchase price.
