Permabond Adhesive Has Fast Fixture Time

Permabond 820 is a modified ethyl cyanoacrylate that has a fast fixture time and temperature resistance up to 200C. This makes it suitable for bonding components in position on dual-sided PCBs prior to wave soldering. Permabond 820 is colourless, with a viscosity of 100CPS. Cyanoacrylate adhesives are single-component adhesives that cure by reacting to small traces of moisture on the surface of the substrates being bonded.

Permabond has a complete line of cyanoacrylates that provide adhesion to different substrates, meeting many application needs with various viscosity, colour, temperature-resistance, gap-filling, cure-speed and compatibility properties available as stock or custom formulation.

The company also manufactures cyanoacrylates (instant adhesives), anaerobics (for threadlocking, retaining, gasketing and pipe sealing), structural adhesives (one or two component epoxies and toughened acrylic adhesives) and UV-visible curable adhesives.

EMKA Releases Fire-Resistant Self-Adhesive Gaskets

EMKA has announced that its 1016 self-adhesive gasket is available in fire-resistant versions to UL94 VO and 94HB ratings, and in EMC formats to address electrical and magnetic interference. The expanded closed-cell neoprene comes in stock strips from 3 to 80mm thick and in standard widths from 10 up to 80mm, with complete custom capability - for example for sheets and punched shapes.

EMC versions of the 1016 program have a conductive external skin to attenuate the transmission of electromagnetic interference across the sealed junction. Expected applications for 1016 gasket include gap sealing, noise reduction - for example from internal equipment - as well as vibration damping and impact cushioning on cabinets, furniture and machinery.

1016 series gaskets are produced in neoprene and EPDM and are are self adhesive to clean, non-porous surfaces such as painted/unpainted metal and plastics, or to seal natural materials such as varnished timber. Neoprene utilised in the 1016 program tolerates working temperatures of 70 to -30C, with fire-resistant versions capable within 85 to -40C. They offer substantial resistance to a range of typical commercial and industrial chemicals and gases.
