Nordson® Systems Deliver Accurate, Efficient Side-Seal/Edge-Seal Solutions For Photovoltaic Modules


27 May 2009

Nordson Corporation (Nasdaq: NDSN) photovoltaic (PV) side-seal/edge-seal systems automate and improve application of moisture barriers in module assembly.  Use of  VersaPail™ or VersaDrum® bulk melters in conjunction with Nordson gear metering dispense applicators enables use of liquefied butyl in place of traditional butyl tape.  This results in accurate, repeatable placement of the PV module moisture barrier along with a faster production process.  

While configurable to meet specific requirements, the typical Nordson system consists of a bulk melter, or even two connected together with auto-changeover, feeding a gear metering dispense applicator.  The applicator offers compact size and key-to-line operation to easily integrate into new or existing manufacturing lines.  The dispensed material, whether butyl or virtually any adhesive or sealant, can be applied as round beads or flat ribbons in customizable widths and thicknesses.

This Nordson side-seal/edge-seal dispensing solution offers several benefits over butyl tape.

  • Ability to use bulk butyl from pails or drums is more cost-efficient.  Tape is expensive as it requires processing of the butyl onto either a backing or a dispense roll.

  • Use of butyl in bulk forms means fewer material refills so reduces downtime.  Tape reels must be refilled often due to limitations of tape reel sizes.

  • Automated butyl application is faster and more accurate.  Manual tape application is labor-intensive and subject to human error.

  • Bulk butyl requires less inventory than tape reels and does not generate the material scrap of tape backing or empty reels.
