Fishman: Problem-Free Cyanoacrylate Dispensing
Cyanoacrylate dispensing system.
Hopkinton, MA — Fishman Corporation's AirFree LDS9000 CA dispensing system reportedly ensures against problems caused by moisture-filled air in dispensing cyanoacrylate adhesives for electronics assembly, as well as for splicing and termination of fiberoptic cables. Instead of air, the unit incorporates a proprietary stepper-motor drive system, in which pressure is applied mechanically to the piston, "pushing" the adhesive.

This action pushes the cyanoacrylate through the barrel reservoir and out the dispensing tip for precise and highly repeatable results (±5 percent). The dispensing system is thus unaffected by changes in temperature, moisture, and viscosity for significantly improved fluid control. To prevent bonding of the cyanoacrylate, the piston and tips are treated with a proprietary non-contaminating release agent.

Cyanoacrylate adhesives have high bond strength and cure rapidly without the need for heat or catalysts. The downside, of course, is that they can cure prematurely, simply in the presence of moisture and air, and can be difficult to handle and dispense. Despite claims to the contrary, traditional dispensing systems, which include pneumatic dispensers, pinch tubes, and diaphragm valves, have not yet solved the problem adequately. The new AirFree LDS9000 CA dispense system reportedly solves these problems.
