Adhesives

Fast curing

Intended for bonding heat sinks or heat-sensitive components to PCBs, the Multi-Cure(R) thermally conductive adhesives can also be used in any application where it is necessary to increase thermal conductivity between assembled parts. The products reportedly cure with UV light, heat, or activator in seconds. The product line includes high, moderate strength, and removable grades; self-shimming grades are also available. They may be dispensed with a range of automatic bench-top applicators and are available in syringes and cartridges up to 600 cc. Dymax Corp.http://rbi.ims.ca/3846-616

Locating patch

Saves time, money

The NYSTAY(R) locating patch is designed to allow threaded and unthreaded fasteners to be temporarily held in place during transport, fabrication, or assembly. The polymer (pre-applied 360 degrees around the fastener) is reportedly soft enough to allow hand assembly and for manufactures to pre-install certain components. It is non-toxic, environmentally safe, and easy to assemble, according to the company. Designed to replace former methods of using plastic washers to hold solid rivets, the product provides a reported increase in productivity while reducing assembly labor costs.
